Abstract

Kraus representation of a damped harmonic oscillator and its application was discussed. A simple operator algebra solution was used for the study. It was found that when the system suffered from amplitude damping, the loss of even numbers of photon left the qubit, whose computational basis was defined by the unchanged even and odd coherent states. It was also found that the loss of an odd number of photon changed the even and odd properties of the qubit.
