I've been studying quantum mechanics and quantum field theory for a few years now and one question continues to bother me. The Schrodinger picture allows for an evolving state, which evolves through ...
If I have a quantum system which I prepare in a certain state, this state then evolves unitarily via a Hamiltonian. Suppose an observer provokes a collapse of the wave function by a certain ...
As an undergrad I was often confused over people's bafflement with Schodinger's cat thought experiment. It seemed obvious to me that the term "observation" referred to the Geiger counter, not the ...
