Comment on Here’s the paper no one read before declaring the demise of modern cryptography

If qbits double every year, we’re at 20 million in 15 years. Changing crypto takes a very long time on some systems. If we’re at ~20000 in 5 years, we better have usable post quantum in place to start mitigations.
But I’m not convinced yet, we’ll have those numbers then. Especially error free qbits…

And then we need to increase coherence time, which is 50ms for the current 433 qubits large chip. Error correction might work, but might not

Error correction does fix that problem but at the cost of increasing the number of qubits needed by a factor of 10x to 100x or so.
