_"a system based on quantum mechanics that can be run using off-the-shelf hardware."_ - https://www.bankinfosecurity.com/blogs/researcher-claims-to-crack-rsa-2048-quantum-computer-p-3536

That sounds a lot like a perpetual motion machine. I'll happily eat this post if it winds up true.

The whole point to a #qubit is we don’t measure it until the end of the computation which, like Schrödinger’s cat, seals its fate.

So if you were to “read” a bunch of qubits to form a #checksum or a #CRC, you’d destroy their quantum nature in the process making your computer not very useful.

You can’t even copy a bit to use something like #triple #redundancy, either. There seems to be no way to practically duplicate a qubit.

#Peter #Schor came up with an answer. Instead of copying a qubit directly, the computer can spread a logical qubit across nine actual qubits. It is then possible to determine if there has been a single physical qubit error using a complicated algorithm.

Later research has dropped the number of qubits required down to five which appears to be the theoretical limit.
