It sounds like we're close. For functional scalable quantum computing, 98% fidelity over many qubits was said to be enough. It would be interesting to see how fidelity scales with qubit count.

I'm pretty sure they need 99.99% for something that will work.
also this is between two qubits. now get like 100+ together with 99.99% then you are slightly closer but still decades away.
so no. they probably another 30 years away

Let me know when I can install it in my PCIE slot.

It maybe sounds like it, but I wouldn’t quit my job just yet :p
