Coherent perfect absorption of quantum light

Coherent perfect absorption (CPA) was introduced as a classical optics phenomenon of standing-wave by subwavelength film. In this paper, we develop theory CPA quantized standing waves taking account thickness the absorber. This approach allows us to merge all known quantum effects under single and introduce other regimes including NOON states with arbitrary number entangled photons, orthogonally squeezed vacuum states, continuous variable Schr\"odinger cat states. Detailed analysis regime sheds light on fundamental aspects dissipation its practical implementation in information.
