Quantum-state input-output relations for absorbing cavities
arXiv:quant-ph/0512184 · doi:10.1088/1464-4266/7/12/035
Abstract
The quantized electromagnetic field inside and outside an absorbing high- cavity is studied, with special emphasis on the absorption losses in the coupling mirror and their influence on the outgoing field. Generalized operator input-output relations are derived, which are used to calculate the Wigner function of the outgoing field. To illustrate the theory, the preparation of the outgoing field in a Schrödinger cat-like state is discussed.
