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

while such machines don't yet exist

Is there really not enough terrifying shit going on in the world that we need to post click bait about hypothetical man-made horrors?

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.

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.

Post-quantum cryptography (PQC), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are currently thought to be secure against a cryptanalytic attack by a quantum computer.
