Google Quantum AI has just proven, beyond any reasonable doubt, that Fault-Tolerant Quantum Computing is possible. For the first time ever, a logical qubit meets all criteria, demonstrating that Quantum Error Correction is effective. Here is the link to the research paper. Many challenges remain. Although Google might in principle achieve low logical error rates …
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 …
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 …
