Breaking encryption with a quantum computer just got 20 times easier (www.newscientist.com)

A quantum computer with a million qubits would be able to crack the vital RSA encryption algorithm, and while such machines don't yet exist, that estimate could still fall further

And a pig with wings could fly. Where are you going to get a million qbits? They are hard pressed to get a dozen of them working without f.ing up completely. And so far they have not produced anything worthwhile with quantum computers, just a few benchmarks.

I thought they had passed 1000 already?

Yeah but they're not reliable, so to get a million reliable qubits you probbaly need like ten million unreliable qubits or a lot of time re-running and processing the results

That was only so-so. In the end they had 400+change usable qubits, and this is just an academic toy, not something usable in reality.
