How is a qubit realized in a cavity?
I do not mean |n> to stand for a n photon state, but rather n=0,1, where we are just talking about an abstract qubit state that is to be realized by a single photon in a cavity. My question is how. What physical states of the photon correspond to |0> and |1> and how are they controlled?
