Have we solved the quantum measurement problem? #quantum #briangreene

And so do you consider the quantum measurement so-called problem to be a problem? — I think it maybe depends a little bit exactly how you define it. When we make a measurement of a small system of a quantum system, what we're basically doing is we're turning it into something like this chair. — Yes, — we're coupling the system to an apparatus which is microscopic and that forces the system to behave the same way as the chair as as you know a big apparatus needle. Particles bounce off of it. you lose information into an environment. And so I would put that with the part of quantum mechanics that we understand quite well. It it's part of the coherence. You're forcing some information into the environment and that explains why there's a definite outcome. — Does this fully satisfy you in the following sense? You're absolutely right. You don't have these weird superpositions, but you do have the state of the chair here as one possibility and the chair over there is another possibility. And there doesn't seem to be anything within the inherent math of quantum mechanics as traditionally formulated that tells us which of those two outcomes is the one that you will C.
