PsiQuantum Progress to Photonic Million Qubit Quantum Computers

December 28, 2022 by Brian Wang

I was at a Q2B conference presentation by PsiQuantum on their work to develop fault-tolerant over one million qubit quantum computers. They are developing new optical and photonic components to achieve truly breakthrough capabilities. They have a staff of over 250 people and have dedicated fabs to create their systems. This seems like a viable …

Xanadu Photonic Quantum Chip Solves Trillions of Times Faster

June 10, 2022 by Brian Wang

Canadian quantum computer company, Xanadu, has used its photonic quantum computer chip, Borealis, to solve a problem in 36 microseconds versus classical supercomputers taking 9000 years. This is 7884 trillion times faster. This runtime advantage is more than 50 million times larger than that of earlier photonic demonstrations. An earlier quantum photonic computer used a …
