One expert warns that the field is overpromising, while another says his firm is on the verge of building “useful” machines.

Scientific American

PsiQuantum CEO Jeremy O’Brien outlines how, by the middle of this decade, PsiQuantum will have completely stood up all the manufacturing lines and processes necessary to begin assembling a final machine: a fault-tolerant, error-corrected quantum computer with hundreds of logical qubits and billions of gates.

2021 APS March Meeting

PsiQuantum is one of a group of leading start-ups in quantum computing. With a more pragmatic approach than its peers, the company hopes to build the world's first 'useful' quantum computer.

Investment Monitor

Quantum computing is now entering the commercial sphere, and given its potential impact on everything from climate change to medical research, no business can afford to ignore it.

Investment Monitor

Jeremy O’Brien, CEO of PsiQuantum, joins Azeem Azhar to explore the exponential advantage quantum computing will bring to problems across science and industry, and talks about how he’s using photonics to build the first productive quantum computer.

Harvard Business Review

We’re excited that our work on Fusion Based Quantum Computing (FBQC) has recently been published in nature communications…

An introduction to fusion-based quantum computing (FBQC) - a model of universal quantum computation in which entangling measurements, called fusions, are performed on the qubits of small constant-sized entangled resource states.

Cornell University Paper

So far, quantum computing has been ruled by ions and electrons, but does its future lie with photons?

Spie - The International Society for Optics and Photonics

Big, stable quantum computers would be useful devices. By exploiting the counterintuitive properties of quantum mechanics they could perform some calculations (though only some) faster than any conceivable non-quantum machine.

Naomi Nickerson - Director of Quantum Architecture at PsiQuantum

Quantum computing may be the most profoundly world-changing technology uncovered to date - it could bring about revolutionary, urgently needed transformations in climate, energy and healthcare. The only outstanding question is this: How do you build such a machine?

Jeremy O'Brien, CEO at PsiQuantum

PsiQuantum, a little-known quantum computing startup, recently received $150 million in a Series C funding round that closed earlier this year.

Forbes

PsiQuantum’s photon-based model is still years away, but the company says it’ll be more powerful than Google’s or IBM’s.

Bloomberg

PsiQuantum Corp. on Monday said it raised $215 million to help it develop a commercial quantum computer more powerful than machines being developed by Google, IBM, Honeywell, and a host of startups and university labs.

Imagine being able to cheaply and easily “suck” carbon directly out of our atmosphere. Such a capability would be hugely powerful in the fight against climate change and advance us towards the ambitious global climate goals set.

Surely that’s science fiction? Well, maybe not. Quantum computing may be just the tool we need to design such a clean, safe and easy-to-deploy innovation.

World Economic Forum Annual Meeting - Jeremy O'Brien, CEO at PsiQuantum

IEEE ICRC 2019 meeting: Pete Shadbolt talks about what’s possible in quantum processing and how it can be improved to provide more useful functionality.

Pete Shadbolt, Co-Founder at PsiQuantum

The science is immature and a multi-purpose quantum computer doesn’t yet exist. But that isn’t stopping investors pouring cash into quantum start-ups.

Scientific American

Nothing has changed the world more than our ability to compute. But the big problems that we’d really like computing to solve are so difficult that, even if Moore’s Law did continue, conventional computers could never solve them. The good news is that a solution is at hand: quantum computing - a drastically different approach to computing that is profound both in terms of the fundamental laws of physics it exploits, and the transformations it will bring about in our lives, society and economy.
