Companies like IBM and (iirc) Google use quantum computers in labs purely as a marketing tool. Each year they proclaim a new success. “Now 4 qubits working!”.

So the average watcher will extrapolate and think: “In 10 or 20 years” the fully working QC will become available.

NOT considering the limits set by the laws of nature.

Time travel will be available sooner than quantum computers. (I mean: both never).

Here's one with 2^3000 parameters:
