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.
In a way, regular computers are also physics experiments. As are fridges and cars. When does an experiment graduate to being a technology?
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.
