Quantum Computing Companies are popping up all over the world as the race to build a working quantum computer heats up. Quantum computers have the potential to revolutionize computing, and these companies are at the forefront of that race. But who are these Quantum Computing Companies? Let’s take a look.
What is Quantum Computing?
Quantum computing (QC) is expected to enable different approaches to computational challenges in industries like healthcare, cybersecurity and the financial sector, yet — unlike other hard tech verticals like artificial intelligence (AI) or virtual reality (VR) — quantum computing seems to be a black box for most other than the specialists working in the industry. Few understand what a quantum computer can do, or what differentiates it from classical computers.
By utilizing specialized hardware and software, quantum computers can tackle tasks such as artificial intelligence, machine learning, and cryptography that are currently beyond the capabilities of conventional computing. For that matter, quantum computing companies develop technologies to enable this cutting-edge technology to become more accessible and useful in everyday life.
The quantum computing industry is rapidly expanding with new innovations being created every day. With that said, let’s take a look at the rise in the number of quantum computing companies over the last 20 years.
The Rise of Quantum Computing Companies
The taxonomy implemented for the classification of the quantum computing companies has three distinct sections, “Quantum Computing Giants”, “Hardware-focused Quantum Computing Companies” and “Software-focused Quantum Computing Companies”. Leveraging the data from our Quantum Intelligence Platform, we have included close to one hundred quantum computing companies in our review. As our Quantum Intelligence Platform has more than 600 organizations in its database, it was inevitable that we would have to omit many of the players across the supply chain. In this article, we have only focused on quantum computing leaders in both hardware and software, as well as the important startups in the industry whose intellectual property is promising.
Furthermore, if you’re interested in diving deeper into the world of quantum computing companies, we have published an in-depth article that explores some of the best quantum computing young companies: 73 Quantum Computing Startups Challenging Industry Leaders.
As quantum computing becomes more mainstream, a richer ecosystem of suppliers, hardware, and software companies will appear. When they do, The Quantum Insider will, as always, cover them in news stories, as well as include them within our platform. For brevity’s sake, we have also excluded the growing industry of quantum security-related players, though some of these have been highlighted in both the hardware and software sections when appropriate. All the listed companies are in alphabetical order.
Top Quantum Computing Companies
Quantum Computing Giants
Of the four major US-founded players in the quantum computing (QC) market consisting of Google, IBM, Microsoft, and AWS Braket (Amazon), only IBM has a legacy in technological innovation that stretches back more than a century. The other three, Google, Microsoft and AWS, have a shorter history in computing. However, though IBM is arguably ahead in terms of hardware and software development in the quantum computing space, the trio chasing IBM are not far behind and are sure to have a positive impact.
Other big players too (which we have included), aware of the huge impact quantum computing and quantum computing companies will have across the board in the mid-to-long term, are setting up their own quantum computing R&D programs in an effort not to get left behind when the industry passes the noisy intermediate-scale quantum (NISQ) era and reaches fault-tolerant capacity and, ultimately, the holy grail of quantum advantage and a new epoch of computation.
1. IBM
Founded in Endicott, New York in 1911 by businessman Charles Ranlett Flint as the Computing-Tabulating-Recording Company (CTR), IBM is one of the world’s tech giants.
“Our goal is to achieve quantum advantage as soon as possible. I don’t like to focus so much on dates for specific items without considering instead an entire roadmap to make it possible. To achieve quantum advantage, we need to both increase the performance of the processors and develop a better understanding of how to deal with errors and program a quantum computer.”
— Jay Gambetta, Vice President, IBM Quantum Lab
In the quantum sphere, the IBM Quantum Composer and the IBM Quantum Lab (previously known collectively as the IBM Quantum Experience) form an online platform allowing public and premium access to cloud-based quantum computing services provided by IBM Quantum. This includes access to a set of IBM’s prototype quantum processors, a set of tutorials on quantum computation and access to an interactive textbook. As of February 2021, there are over 20 devices on the service, six of which are freely available to the public. This service can be used to run algorithms and experiments and explore tutorials and simulations around what might be possible with quantum computing.
The IBM Quantum Lab is led by Vice President, Jay Gambetta, an IBM Fellow.

2. Google Quantum AI
Along with IBM, Google Quantum AI is a leading player in full-stack capabilities in quantum computing. Google Quantum AI is advancing the state of the art of quantum computing and developing the tools for researchers to operate beyond classical capabilities.
The nerve centre for Google’s quantum activities is The Quantum Artificial Intelligence Lab, a joint initiative between Google, NASA and the Universities Space Research Association, it was founded in 2013 and was the one responsible for the announcement it had achieved quantum supremacy back in October 2019.
Google’s software and hardware are specifically designed for building novel quantum algorithms to help solve near-term applications for practical problems. These include Cirq, a Python software library for writing, manipulating, and optimizing quantum circuits, and then running them on quantum computers and quantum simulators; OpenFermion, a library for compiling and analyzing quantum algorithms to simulate fermionic systems, including quantum chemistry; and TensorFlow Quantum (TFQ), a quantum machine library for rapid prototyping of hybrid quantum-classical ML models.
Led by Engineering Director, Hartmut Neven, the goal of Google Quantum AI is to pioneer research on how quantum computing might help with machine learning and other difficult computer science problems. The lab is hosted at NASA’s Ames Research Center. Part of Google’s strategy included its quantum roadmap.

3. Microsoft
Another of the big players, Microsoft is the provider of the world’s first full-stack, open cloud quantum computing ecosystem, featuring solutions, software and hardware delivered through Azure.
Although Microsoft was founded in 1975, the roots of Microsoft’s research into quantum had two teams interested in quantum computing, the QuArC team based in Redmond, Washington, directed by Krysta Svore. This team explored the construction of quantum circuitry. The second, located in Santa Barbara and led by Michael Freedman, was Station Q, which was researching topological quantum computing.
In September 2017, during a Microsoft Ignite Keynote, Microsoft announced the imminent release of a new quantum computing programming language, Q#, which was eventually rolled out in December of that year, as part of the company’s Quantum Development Kit.
However, Microsoft’s quantum program hasn’t gone without controversy: in 2018 a Microsoft-led team of scientists — headed by physicist Leo Kouwenhoven at the Delft University of Technology in the Netherlands — retracted a high-profile paper that the company touted as a key breakthrough in the creation of practical quantum computing, claiming to have found evidence of Majorana particles, long-theorized but never conclusively detected.
“Microsoft has taken this very risky but high reward approach in trying to make a qubit which on the theory side looks like the very best qubit you can get. But the challenge was that nobody has really seen these Majorana zero modes in real life. But we have done that now, and that’s super exciting. We have to continue to evolve our engineering capabilities, but it really looks like there is a path towards scalable quantum computing now.”
— Peter Krogstrup, Scientific Director, Microsoft’s Quantum Materials Lab in Lyngby, Denmark
At Build 2019, Microsoft announced that it is open sourcing the Quantum Development Kit, including its Q# compilers and simulators.
Microsoft quantum initiative is steered by Julie Love, Partner and Product Leader for Quantum Computing, with Bettina Heim currently leading the Q# language development effort.
4. AWS Braket
Amazon Braket is a fully managed quantum computing service designed to help speed up scientific research and software development for quantum computing.
“We felt there was enough of a community to really get the most out of a quantum platform, so that’s why we launched Braket. It’s designed to get people up and running quickly, removing the barriers to playing with this technology and fundamentally trying to be a catalyst for innovation.
Fundamentally, AWS all about enabling third parties to build other services and build applications on top of the platform — and that’s exactly the same with quantum computers.”
— Richard Moulds, General Manager, Amazon Braket (AWS Quantum Computing Service)
Led by Simone Severini, AWS Director of Quantum Computing and Professor of Physics of Information at University College London, Amazon Braket is a service that provides access to different types of quantum computers to customers via the cloud. Available since 2020, the AWS Braket service allows anyone to open an account, log in and pay as you go using the quantum cloud service that leverages quantum annealers from D-Wave, IonQ’s gate-based ion-trap processors, the gate-based superconducting processor offering from Rigetti Computing and Oxford Quantum Circuits, and the gate-based photonic quantum computers from Xanadu.
Other features include a hardware-agnostic developer framework, which simplifies the process of designing and executing quantum algorithms, fully managed Jupyter notebooks, pre-built algorithms and tutorials, a choice of simulation tools, and many other interesting possibilities.
5. Alibaba Group
Partnering with the Chinese Academy of Science, Alibaba Group’s cloud computing subsidiary has established the Alibaba Quantum Computing Laboratory in Shanghai, China. A member of the international quantum computing community the Alibaba Group’s quantum efforts embrace the idea of open-source projects in the space
In charge of all this is Yaoyun Shi, Head of Quantum Lab, where he leads projects that include the Alibaba Cloud Quantum Development Platform (ACQDP) — a simulator-driven development tool for quantum algorithms and quantum computers.
6. Atos Quantum
Atos Quantum is a group within the French multinational company Atos that specializes in quantum technology. Atos Quantum has released a product called the Atos Quantum Learning Machine, a classical computer that can simulate a quantum system using anywhere between 30 and 40 qubits, depending upon the specific configuration. Associated with this product, Atos Quantum provides a universal quantum assembly programming language called AQASM along with other software to allow researchers, engineers, and students to develop and experiment with quantum software.
In the field of quantum hybridization, Atos Quantum is the only player already enabling several applications — in the areas of chemistry, such as catalysis design for nitrogen fixation, and for the optimization of smart grids. Atos is also involved in two additional quantum hybridization projects, which are currently being launched.
Atos is one of the first quantum computing companies to adopt a hardware-agnostic approach in developing quantum-powered supercomputers, as well as providing end-user applications. Atos’ ambition is to be a major player in multiple domains among which are quantum programming and simulation, the next-generation quantum-powered supercomputers, consulting services, and of course, quantum-safe cybersecurity.
“Atos launched the Atos Quantum Learning Machine (QLM) in 2017, a quantum appliance emulating almost all target quantum processing units with abstractions to connect to real quantum computing hardware when available. We have been very successful with the QLM in large academics or research centers on all continents. In 2021, there was a shift of many commercial companies starting to work on real use cases, and the QLM is the best platform to start these projects without waiting for hardware to be available at scale.
— Eric Eppe, Head of Portfolio & Solutions, HPC & Quantum, Atos
Atos plays a central role in European-funded quantum computing projects. It is cooperating with NISC QPU makers to develop new technologies and increase their effectiveness in a hybrid computing scenario. This includes, but is not limited to, hybrid frameworks, containerization, parallelization, VQE, GPU usage and more.
In charge is Eric Eppe, Head of Portfolio & Solutions, HPC & Quantum. Atos also boasts The Quantum Advisory Board, made up of universally recognized quantum physicists that include Alain Aspect, Professor at the Institut d’Optique Graduate School, Université Paris-Saclay and at Ecole Polytechnique, Institut Polytechnique de Paris, Artur Ekert, Professor of Quantum Physics at the Mathematical Institute, University of Oxford and Founding Director of the Centre for Quantum Technologies in Singapore and Nobel laureate in Physics, Serge Haroche, Professor emeritus at the Collège de France.

7. Baidu
Like Alibaba, Baidu comes from China. Its quantum program includes the launch of an institute for quantum computing dedicated to the application of quantum computing software and information technology. Called the Baidu Quantum Computing Institute led by Professor Duan Runyao, who had been the director of the Centre for Quantum Software and Information at the University of Technology Sydney (UTS), Baidu’s intention is to see quantum technology useful across several verticals like artificial intelligence (AI) and machine learning (ML).
“With Qian Shi and Liang Xi, users can create quantum algorithms and use quantum computing power without developing their own quantum hardware, control systems, or programming languages. Baidu’s innovations make it possible to access quantum computing anytime and anywhere, even via smartphone. Baidu’s platform is also instantly compatible with a wide range of quantum chips, meaning ‘plug-and-play’ access is now a reality.”
— Runyao Duan, Director of the Institute for Quantum Computing, Baidu
Baidu says it has designed a quantum hardware-software integration solution called Liang Xi. The system can plug into Qian Shi and other third-party quantum computers, including a 10-qubit superconducting quantum device and a trapped ion quantum device developed by the Chinese Academy of Sciences.

8. Intel
Like IBM, Intel has a storied history in the semiconductor industry, having been founded in Mountain View, California, in 1968 by Gordon Moore of “Moore’s law” fame and Robert Noyce, a physicist and co-inventor of the integrated circuit.
Leading the charge is Intel’s Director of Quantum Hardware, James Clarke. Intel Labs, the R&D arm of the company, is leveraging its expertise in high-volume transistor manufacturing to develop ‘hot’ silicon spin-qubits, much smaller computing devices that operate at higher temperatures. Second, the Horse Ridge II cryogenic quantum control chip provides tighter integration. And third, the cryoprober enables high-volume testing that is helping to accelerate commercialization.
Intel is working on both superconducting and spin qubits, though research on superconducting seems to be limited to their academic affiliations at Qutech (Delft university), whereas spin qubits are the main focus with activities at Qutech and in-house.
“Another big differentiator between Google, IBM and Intel is the type of qubit we are studying. Our qubit looks a lot like a conventional transistor, and conventional transistors are extremely smaller than a superconducting qubit (used by Google and IBM) — our spin qubit technology is roughly a million times smaller than a superconducting qubit. So the hope is that we could scale this technology a lot better than the competition.”
— James Clarke, Director of Quantum Hardware, Intel

Top Hardware-Focused Quantum Computing Organizations
1. Alice & Bob
French quantum computing company, Alice & Bob is working towards building an error-corrected, fault-tolerant quantum computer. Its research is focused on self-correcting superconducting quantum bits, and cat qubits.
Alice & Bob’s technology detail is developing self-correcting superconducting quantum bits, enabling fault-tolerant quantum computing. In March 2022, the business announced that it had solved one of the major error correction hurdles for qubits (bit flips). In this work, they demonstrated that their cat-qubit stabilization scheme was compatible with macroscopic bit-flip times: increasing resilience to bit-flip errors from a previous record of a few milliseconds to 2 minutes.
“In order to fully realize the promise of quantum computing, we have to get a grip on handling quantum errors. Surface codes drive the field toward a scaling bottleneck. Cat qubits enable a roadmap using linear code, with dramatically reduced overhead. […]”
— Théau Peronnin, CEO Alice & Bob
This quantum computing startup, based in Paris, was founded in 2020 by Raphaël Lescanne and Théau Péronnin. On the funding front, Alice & Bob has raised a total of $33 million.

2. Alpine Quantum Technologies
With headquarters in Innsbruck, Austria, Alpine Quantum Technologies (AQT) develops trapped ion quantum devices by working on building a full quantum computer using trapped ion technology.
Beyond state-of-the-art applications such as factoring, simulations on high-energy physics or quantum chemistry, AQT ion-trap technologies offer a clear roadmap to large-scale quantum computers, from scalable ion-trap processors to photonic networks connecting quantum computers.
“If you’ve ever done a tour of a lab with a superconducting quantum computer, you’ll have noticed these sort of ‘oil barrel’ hanging from the ceiling making a ‘tchk, tchk, tchk’ sound. That’s the compressor, running with helium, because it needs to be cold. Our trapped ion project is room temperature. So, besides the vacuum can which is closed, the entire device is standing in a normal office and you can touch all the components and nothing is going to freeze or do anything to you. We are still working on the prototype, but it seems like we can run the entire quantum computer from a normal power plug in the wall. And the next thing is: because the power consumption is low and it works at room temperature, it’s easy to envision our device as being mobile.”
— Thomas Monz, CEO, AQT
With some $34 million raised to date, AQT was founded in 2017 by Professor Rainer Blatt, Dr Thomas Monz and Professor Peter Zoller.

11. EeroQ
EeroQ is building a quantum computer chip that uses electrons on superfluid helium. Its technological detail is electrons on helium quantum computers. These may offer several advantages over other QC models, such as scalability, potentially faster gate operations, and because it promotes a less noisy quantum environment, longer coherence times. Longer coherence times are critical to create stable, less error-prone quantum calculations.
“Electrons on helium is a novel technology and very different from other qubit platforms, and it’s quite fun to describe. In our approach to building a quantum computer, the qubit is an electron trapped in vacuum above the surface of superfluid helium, using microwaves for quantum logic gates. This is one of the cleanest systems known to exist, so while it’s challenging to work with it offers a somewhat natural “home” for quantum computation.”
— Nick Farina, CEO, EeroQ
Based in New York City, this quantum computing company was founded in 2016 by Nick Farina, Faye Wattleton, Professor Johannes Pollanen, Dr. David Rees, David Ferguson, and Hannah Parnes.

The Company currently has two quantum computers (which it describes as leading) and you can access it through Amazon Braket. In May 2022, the company announced IonQ Forte, its latest generation of quantum systems. Forte is expected to be initially available for select developers, partners, and researchers in 2022 and is expected to be available for broader customer access in 2023. The system features acousto-optic deflector (AOD) technology, which allows IonQ to dynamically direct laser beams that drive quantum gates towards individual ions. The AOD is designed to minimize noise and overcome variations in ion position, improving fidelity in long chains of trapped ions, which is crucial for scaling quantum computers. In addition, key parameters, including qubit and gate configuration, can be tailored to user needs, creating a truly dynamic and flexible system.
“IonQ Forte is further proof that high-performance quantum computers can be designed and built so both qubit count and gate fidelity improve simultaneously. We expect that this will lead to quantum computers with increasing algorithmic qubit numbers that will enable the search for solutions to the most complex problems of our time. IonQ’s quantum systems, including Aria and Forte, are at the forefront of achieving practical utility. The most impactful quantum computing applications will come to light when leading innovators seeking new ways to tackle their formidable problems get to work with the best systems, and customize them for their unique needs. We can’t wait to get these systems in people’s hands.”
— Jungsang Kim, CTO, IonQ
Based in College Park, Maryland, IonQ was founded in 2015 by Chris Monroe and Jungsang Kim with $2 million in Seed funding from New Enterprise Associates, a license to core technology from the University of Maryland and Duke University.

Based in London, UK, ORCA Computing was founded in 2019 by Richard Murray, Cristina Escoda, Josh Nunn, and Ian Walmsley and is developing a modular quantum computing platform using photonic technology.
“One of the most interesting properties of photonic qubits is that they are ‘in flight’. You can pulse a source so that it produces multiple photons in a chain within a single length of optical fibre”. A highly efficient source could produce a chain of a million photons, although it would not be error corrected, our early results show that this could be an attractive method to scale the quantum system.”
— Richard Murray, CEO, ORCA Computing
Having raised nearly $17 million in funding, ORCA’s core offering is its ability to store photons in its unique quantum memory. This acts as a buffer, overcoming the core challenge of photonic quantum computing; namely the inherently probabilistic nature of generating qubits. In June 2022, the company announced it is partnering with the UK’s Ministry of Defence to develop a quantum computer to explore applications in defence.

17. Oxford Ionics
Founded in 2019, Oxford Ionics is creating high-performance quantum computers by combining trapped ions qubits with proprietary noiseless electronic qubit control technology.
Founders Chris Ballance and Tom Harty, Oxford Ionics is developing high-performance quantum computers by associating an ion-trap model with its Noiseless Electronic Qubit Control technology, which aims to reduce quantum noise (the amalgam of errors and interferences created by variations in the photon signature and the electromagnetic fields inside the device). The combination of Oxford Ionics’ unique electronic qubit control (EQC) technology with Infineon’s world-leading engineering and manufacturing capabilities, as well as expertise in quantum technology, will lay the foundations for the industrial production of QPUs offering hundreds of qubits within the next five years. The goal is to move quantum computing technology out of the research lab into real industrial solutions.
“The great challenge in quantum computing is scaling whilst improving performance. There are technologies that can be fabricated at scale but don’t perform, and there are technologies that perform but don’t scale. Our electronic control is uniquely placed to do both. Working with Infineon and its mature and flexible semiconductor process, allows us to speed up the accessibility of a commercial QPU. Due to our market-leading error rates, these processors need up to 10,000 times fewer qubits to solve useful problems than other technologies.”
— Chris Ballance, Co-Founder, Oxford Ionics.
The quantum computing startup has raised just over $3 million in outside money since it was founded.

Its novel solutions include post-RSA cybersecurity modules that migrate enterprises to higher levels of security, enabling post-quantum cryptography (PQC) in line with the new standards that are now emerging in this field.
A spinoff company from Alphabet (Google’s parent company), SandboxAQ was reportedly a passion project of Google founder Sergey Brin. Led by Jack Hidary the business raised $500 million in outside funding in March of this year backed by Section 32, Thomas Tull, Paladin Capital Group, Guggenheim Investments, T.Rowe Price, Eric Schmidt, Breyer Capital, Time Ventures, In-Q-Tel, Parkway Venture Capital.
“The value-add we [SandboxAQ] offer is the following: The discovery tool and the encryption modules all have our machine learning modules in them. Why machine learning? Is it just pixie dust we have to add to everything? No. The reason is that, coming out of the NIST process, we don’t have just one protocol: We have multiple valid post-RSA protocols.
For a large enterprise architecture, we need a control plane and a data plane, and we need to separate the control plane from the data plane. The data plane is the encryption plane. That’s where the encryption happens using the post-RSA protocols. The control plane is where the machine learning sits, to choose in real time the parameters and which protocol to use. Some protocols are faster, some are a bit slower, some offer a bit more security, some sufficient but a bit less. An ML model is necessary to make these real-time choices.
We offer a lot of value-add with our deep heritage of machine learning and our knowledge and expertise there, suffused with our understanding and deep expertise in quantum-safe cryptography. Bringing these two together, that’s where the value-add is.”

35. Zapata Computing
Zapata Computing is based in Boston, Massachusetts and develops quantum software and algorithms for business. Its core proposition is Orquestra, which the company describes as the first unified quantum operating environment. This allows users to compose quantum-enabled workflows and execute them across classical and quantum technologies. The business also looks to actively help customers use quantum computers for real-world problems.
“What we showed [Zapata] in our papers is if you have a quantum source of bit strings that comes from that source of supremacy (think of the quantum computer a la Google), you get a better distribution and a better handwriting sample and a better portfolio optimization than you can with classical machine work. We can do that today.
So, what we’ve done is we’ve taken a quantum-enhanced neural network approach to basically put our quantum spy on that solver. We’re feeding into a classical neural network workflow that already exists and is already in production in a lot of places. The great thing is their cost function, their model, already exists too; we just put a little quantum spy on it. We think it’s pretty clever, and it’s patented, and very disruptive. We’re able to basically model the distribution of the good answers for any software.”

Current QC Trends
Although using the word “trend” can be off-putting for some, particularly for those working in science and the hard tech sectors where researchers sometimes spend years, even decades, developing their ideas and IP, several trends in quantum computing are clear to see in 2022.
One is the idea that quantum-based encryption is a near-term realization. Worries that criminals are “harvesting data now ready to decrypt later” when we reach quantum computing functionality have got many companies and organizations prepared to turn to quantum-proof security alternatives for data transmissions.
Secondly, there are services providing quantum computing as a service (QCaaS). With the rise of the cloud and available platforms like IBM, Microsoft and AWS Braket, the quantum revolution is definitely underway.
Last, we have the quantum internet, designed to communicate by leveraging the spooky laws of quantum mechanics. Though it still could be some time away, experts in the field are openly talking about it, especially since China has made inroads in this vertical.
