Company on track to build a fault-tolerant quantum computer ready to tackle breakthrough applications in climate, energy, life sciences, and beyond.

Quantum computing is in many senses the holy grail of high-performance computing. The technology promises to dramatically accelerate simulations, machine learning, and perhaps most terrifyingly, render modern encryption schemes mute. And like the holy grail, making good on these promises remains elusive. While progress is being made in the field, many unsolved challenges remain.

PsiQuantum's singular vision is still to build an error-corrected million qubit quantum machine that could use tens of billions of gates on hundreds of logical cubits. If the PsiQuantum-GLOBALFOUNDRIES project is successful, it will create shifts in the market, impact society, as well as change how we think about and deploy large quantum devices.

Chip manufacturing giant, GLOBALFOUNDRIES, has struck up a unique arrangement with PsiQuantum, an ambitious quantum startup to share knowledge that could help turn standard photonics processing technology into a qubit factory.

The companies have demonstrated a world-first ability to manufacture core quantum components, such as single-photon sources and single-photon detectors, with precision and in volume, using the standard manufacturing processes of GF’s world-leading semiconductor fab.

Palo Alto, California-based PsiQuantum has plans to create a million-qubit quantum computer. Globalfoundries is a major chipmaker that will manufacture the silicon photonic and electronic chips that are part of PsiQuantum's Q1 system.

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.
