Since we didn’t have time in Wednesday’s class to get to the “meaty” debate about quantum computing’s possible relevance to the interpretation of quantum mechanics, this week’s discussion topics will be unusually broad.
Does quantum mechanics need an “interpretation”? If so, why? Exactly what questions does an interpretation need to answer? Do you find any of the currently-extant interpretations satisfactory? Which ones, and why?
More specifically: is the Bayesian/neo-Copenhagen account really an “interpretation” at all, or is it more like a principled refusal even to discuss the measurement problem? What is the measurement problem?
If one accepts the Many-Worlds account, what meaning should one attach to probabilistic claims? (Does “this detector has a 30% chance of registering a photon” mean it will occur in 30% of universes-weighted-by-mod-squared-amplitudes?)
