Annals of Physics Classical impurities and boundary Majorana zero

... barrier which blocks its further propagation. Mixing of the boundary Majorana states located at the opposite boundaries thus becomes impossible; hence an exact Z2 degeneracy of the ground state. Let us make this statement more precise. Consider a QIC with a zero-h impurity, say at n = 0: H = ...

Understanding the Mach-Zehnder Interferometer (MZI)

... For simplicity, we will assume that a photon can only reflect from one of the two surfaces of the identical half-silvered mirrors (beam splitters) BS1 and BS2 because of anti-reflection coatings. The detectors D1 and D2 are point detectors located symmetrically with respect to the other components o ...
