Palo Alto, CA, USA
Posted on Friday, July 14, 2023

We are on a mission to build the world’s first large-scale, commercially viable, 1 million-plus qubit quantum computer, powered by breakthroughs in silicon photonics and quantum architecture. We were founded in 2016 by the world’s foremost experts in photonic quantum computing and have assembled a world class team dedicated to bringing the world-changing benefits of quantum computing into reality.

Quantum computing is anticipated to unlock the solution to otherwise impossible computational tasks, with potential impact across all of science and technology. By harnessing the laws of quantum physics, quantum computers are expected to dramatically outperform even the most powerful supercomputers, enabling extraordinary advances across a broad range of applications including climate, energy, healthcare, finance, agriculture, transportation, materials design, and more.

In many areas of scientific and technical inquiry, humanity has reached the limit of what even the most powerful existing (or future) supercomputers can do--but quantum computers are poised to crack problems that are simply out of humanity’s reach with traditional computers. With applications across climate, healthcare, energy, finance, agriculture, transportation, materials design and more, quantum computing will tackle some of the most urgent practical challenges we face, as well as deliver entirely new industries.

PsiQuantum is uniquely positioned to deliver on the promise of quantum computing. We have already demonstrated that it’s possible to manufacture core quantum components using the standard and scalable manufacturing processes of a world-leading semiconductor fab.

There’s more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!
