1. AWS


One of the largest companies in the world founded by the second richest human on earth, Jeff Bezos, AWS — known to most people as Amazon — launched the AWS Center for Quantum Computing in 2019 with the goal of accelerating the development of quantum computing technologies and applications. Teams will focus on developing more powerful quantum computing hardware and identifying new applications for quantum technologies.

Late in 2021, AWS opened a new facility for quantum computing at the California Institute of Technology (Caltech) with the ambitious goal of building a “fault-tolerant” quantum computer.

Via a fully managed quantum computing service designed to help speed up scientific research and software development for quantum computing called Amazon Bracket, AWS provides access to quantum annealing technology based on superconducting qubits from D-Wave, as well as access to quantum hardware based on the gate model from Rigetti Computing and CQC.

2. Google Quantum AI

A multinational that needs no introduction, Google Quantum AI’s quantum computing service provides chaperoned access to NISQ processors and its simulator for researchers who aim to advance the state-of-the-art in quantum computing and publicly share their results in algorithms, applications, tools, and processor characterizations.

Google offers a quantum computing service to scientists developing algorithms for noisy-intermediate-scale quantum processors like Sycamore. The goal is to advance NISQ state-of-the-art in new algorithms, tools, and characterizations that lead to useful applications. Approved projects will run programs on Sycamore via the company’s Quantum Engine API, and user feedback will improve the service.

Everything happens in Google’s quantum research lab located in Santa Barbara, California, where fleets of cryostats, dedicated workshops, and a superconducting qubit fab bring together engineers and researchers to implement and deliver NISQ-era processors with increasing quantum computational volumes — stepping stones to our error-corrected quantum computer.

Google was founded in 1996 by Larry Paige and Sergei Brin.

3. Intel


Another world-dominating multinational player, Intel’s contribution to the QC race using superconducting qubits consists of working to achieve quantum practicality, the transition of quantum technology from the lab to commercial quantum systems that solve real-world problems. With the help of industry and academic partners, Intel has made significant progress in realizing this vision.

Founded in Mountain View, California by Gordon Moore and Robert Noyce in 1968, Intel is now headquartered in Santa Clara, California.

4. Oxford Quantum Circuits (OQC)

OQC has built the UK’s most advanced quantum computers, the only ones commercially available in the country. It has also launched the UK’s first Quantum Computing as-a-Service (QCaaS), bringing quantum to the enterprise, at the fingertips of our customers and partners.

5. Anyon Systems


A Canadian concern from Dorval, Quebec, Anyon Systems was founded in 2014 by Alireza Najafi-Yazdi. Its goal since then has been to revolutionize the world by introducing quantum computing platforms.

Anyon has developed unique technologies involving the full vertical hardware stack of a quantum computer by designing and manufacturing superconducting quantum processing units (QPUs), quantum control electronics as well as ultra-low temperature cryogenics systems which host QPUs.

Anyon Systems now delivers turn-key Near-term, Intermediate-Scale, Quantum (NISQ) computers to early adopters. These machines enable our clients to get started with their quantum R&D program, build eco-systems, and stay ahead of the competition.

6. IBM

Like Google and Intel, IBM is a giant of the tech world and a leading proponent of QC. IBM’s full-stack approach delivers the best of IBM’s quantum computing systems together with the most complete suite of quantum software tools and cloud services.

The Armonk, New York-based company’s 127-qubit Eagle processor takes us into uncharted computational territory. This device embodies several important advances in our approach to hardware design, and marks a crucial stage in our climb toward quantum advantage.

Founded in 1911 as the Computing-Tabulating-Recording Company (CTR), the company was renamed “International Business Machines” (IBM) in 1924.

7. EeroQ

EeroQ is a New York and Lansing, Michigan-based leader (with plans to move its headquarters to The Terminal in Chicago, Illinois) in the field of quantum hardware, building a universal quantum computer using electrons on helium (eHe).

Founded in 2016 by Professor Stephen Lyon, Professor Johannes Pollanen, Faye Wattleton, Nick Farina, and Dave Ferguson, at the heart of EeroQ’s technology is the trapping and control of individual electrons floating above pools of superfluid helium. These electrons form the qubits of its quantum computer, and the purity of the superfluid helium protects the intrinsic quantum properties of each electron. EeroQ’s ultimate goal is to build a large-scale quantum computer based on quantum magnetic (spin) state of these trapped electrons.

8. Rigetti Computing


Fresh off closing a SPAC deal to debut on the NYSE, Rigetti Computing (Nasdaq: RGTI) is building the world’s most powerful computers to help solve humanity’s most pressing and important problems. These systems will perform computations that today’s fastest supercomputers are incapable of — unlocking entirely new classes of problems and offering a direct path to solutions. Rigetti believes quantum computing is going to significantly affect health care, how we treat disease, how we generate energy, and how we feed humanity. Our superconducting quantum computing systems are available over the cloud via Rigetti Quantum Cloud Services.
