How can something that is NOT understood be replicated? Dbl slit and quantum dots are not even almost the same thing as alleged quantum computing. And two things do not equate the entirety of quantum mechanics. And even with dbl slit, there is still open debate as to the reason for it.
Its all marketing. Just like AI (artificial yes, intelligent no and NEVER will be). Add either to the name of something, and you can add a lot to the price.
