Photonics Market

As per the report, the Global Photonics Market — Forecasts from 2020 to 2025 published in April of 2020 in Research and Markets, the global photonics market is projected to grow at a CAGR of 5.85% to reach US$829.775 billion by mid-decade, from US$589.950 billion in 2019.

This is also good news for the quantum tech industry, which is set to grow, too. With more quantum computing startups being founded all the time, and with a fair proportion of them based on photonics, TQD thought it a good idea to list the top photonics companies as of 2024. A good indicator of the healthy state of the photonics industry, and how it can thrive further, is that five of the nineteen photonics companies listed here were founded in 2019.

For the avoidance of doubt, we have mixed up the hardware companies providing the underlying photonics equipment, as well as the startups leveraging the photonics equipment to advance quantum technologies.


19 Top Photonics Companies

1.AegiQ (UK)

AegiQ (UK)

AegiQ, is one of the top photonics companies formed as a spinoff from the University of Sheffield. It was founded in 2019 by Maksym Sich, Scott Dufferwiel, Maurice Skolnick, and Jon Heffernan. Their main goal is to manufacture high-calibre quantum photonic applications.

“Thousands of AegiQ systems will be required in each data centre around the world, as they transition to using quantum technologies for communication and cloud computing. Deploying our scalable technology with mass production capabilities into initiatives like this project will position the UK as a world-leader in manufacturing quantum communications.”

— Max Sich, CEO and co-founder of AegiQ

To achieve this, AegiQ secured £1.4 million in funding from Innovate UK in September 2020. The money will go towards developing secure quantum communications for fibre-optic and satellite-based applications.

2.Cambridge Quantum Computing (UK)

Cambridge Quantum Computing (UK)

Cambridge Quantum Computing (CQC) needs no introduction: a world leader in quantum algorithms and software, the CQC’s technology is assisting chemical, energy, financial, and material science companies to see the quantum future.

Founded in 2014 by CEO Ilyas Khan, a British technologist, seasoned businessman and philanthropist (and former chairman of the Stephen Hawking Foundation), the company’s IronBridge™ quantum photonic cryptography device ‘is the only encryption process that ensures device independence and source certifiability to be used for post-quantum encryption algorithms, cached entropy generation for IoT devices, key generation for certificates, quantum watermarking and many other use cases and can be generated by general-purpose NISQ era quantum computers that are currently available’.

“We knew from the very beginning that if we could help the manufacturers and builders of early-stage quantum computers be the best that they could be by getting the best out of their devices and quantum processors, then we would be making a genuine and lasting impact.”

— Ilyas Khan, exclusive interview TQD 2020

Things are not only looking on the up for CQC with innovation but on the human resources side too: Bob Coecke, a professor at the University of Oxford in quantum foundations, logic and structures, joins as chief scientist, having worked as a senior scientific advisor before at CQC.

Scientists at the National Physical Laboratory (NPL) are working with Cambridge Quantum Computing (CQC) to accelerate research and development to support the commercialisation and optimisation of their quantum technologies, such as IronBridge™, and help with the characterisation of photonic components.

A $45 million financing round in December, bringing a $450 million post-money valuation to the company, only adds credence that CQC is one of the leading photonics companies in the industry.

12. Photonic Inc (Canada)

Photonic Inc (Canada)


The intention is simple: creating left-field quantum technologies in silicon photonic spins. Canada’s Photonic Inc. was founded in Vancouver, Canada, in 2016.

We’re convinced that silicon — the very backbone of modern telecommunications and computation — is the missing component needed to finally realize the goal of a global quantum network

— Photonic Inc

With roots firmly placed in the Silicon Quantum Technology Lab at Simon Fraser University, the startup’s proprietary technology in photon spin interfaces in silicon, silicon integrated photonics, and quantum optics. Photonic is manufacturing two-centimetre square silicon chips capable of holding million-plus qubits.

And yeah, for all you physicists out there, ‘you read that correctly’.

Founder and chief quantum officer (CQO — love the epithet) at Photonic is Stephanie Simmons.

13.PsiQuantum (US)

PsiQuantum (US)

Founded in 2016 by Jeremy O’Brien, Pete Shadbolt, Mark Thompson, and Terry Rudolph, PsiQuantum is based in Palo Alto, California. The startup’s photonics-based, fault tolerance approach to building a universal quantum computer in a CMOS silicon fab is fully in gear. Still, in stealth mode for all sense and purposes, the startup believes wholeheartedly silicon photonic qubits are the best way forward to solve real-world problems using quantum computers.

What is more extraordinary about PsiQuantum, however, is the amount of money the company has raised since the summer of 2016: $508.5 million, the last funding coming in the spring of 2020 in a Series C round valued at $215 million, which was led by Atomico. With that kind of money at its disposal, PsiQuantum we’re sure to hear a lot more from them.

19.Xanadu (Canada)

Xanadu (Canada)


We finish the list with what is one of the most high-profile photonic companies in the quantum tech industry, Xanadu. Founded in 2016 by CEO Christian Weedbrook, Xanadu’s mission “is to build quantum computers that are useful and available to people everywhere”.

The Photonic Advantage: Fastest path to scalable, robust, and practical quantum computers

— Xanadu

Taking a full-stack approach to manufacturing hardware and software, as well as research with a selection of strategic partners, Xanadu’s Quantum Cloud (XQC) service, Strawberry Fields application library and PennyLane — an open-source project for quantum ML — mean that the Canadian company is at the cutting edge of developments in QIS.

The release of the world’s first publicly available photonic quantum cloud platform last September, where developers can access gate-based photonic quantum processors, in 8, 12, and in the future 24-qubit machines, shouldn’t do any harm to the company’s credibility, either — so, too, the apparent obsession Xanadu has for The Beatles.

Since 2016, the company has managed to raise over $30 million, with a mixture of non-equity assistance, grants, Seed and Series A rounds.
