The problem is that it is impossible to say exactly whether a quantum computer works or not :)
by Raegdan:
Heisenberg’s quantum computer: If we know it works, we don’t know it doesn’t work, and vice versa.

Schrödinger’s quantum computer works and doesn’t work at the same time until we decide to check whether it still works. If it works - it will no longer be turned off; if it does not work - you can safely throw it out, because. He will never earn again.

Einstein’s quantum computer: doesn’t work, won’t work, and generally (shows language) you’ll build it – because God doesn’t play on a quantum computer!
