So I joust found this brilliant scientific paper called "Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog" which mocks quantum computer researchers for optimising factorisation of prime numbers in a way, so that it is as easy as possible to calculate them with a quantum computer. While you may not understand the technical or mathematical explanations they include a lot of jokes and its very funny to read. One of the jokes is,that they call quantum computers a "physics experiment", which is the explanation behind this joke.
They are pointing out in this article that the way that the problem is devised for the computer makes it basically already solved. The quantum computer get a list of all the factors and, after a bunch of hand waving, picks one. Something a vic20 an abacus and a dog can all do too.
