Reality check: no one has ever built a quantum computer with qubits lasting more than a tiny fraction of a second, and quite possibly they never will.

I'll take that bet. Since we currently operate with 9s coherence times in my own lab. And the record is about an hour.https://arxiv.org/abs/2008.00251
Read my tweet. I'm talking about a working computer, not an isolated qubit.

I know nuclear free Si28 spin in AU (nearby lab) which has a few days, if I am not wrong.

Not a computer.

Sorry sir we perform quantum computations for chemistry using our system with 9s coherence times. So, incorrect.

There are lots of critiques to be made about the progress, challenges, and hype in
#quantumcomputing. You made a straight factual assertion which is simply incorrect. It's ok, we all make mistakes. - Näytä vastaukset
