Abstract
We present a general formalism and specific implementations of quantum gates based on interaction of single photons with open dissipative nanocavities containing ensembles of quantum emitters. Rich dynamics of entangled bright and dark states of quantum emitters coupled to a nanocavity field gives rise to efficient manipulation of the quantum state of an incident photon. As a simple example, we analyze the realization of a controlled-NOT gate in which the cavity loaded with quantum emitters serves as a control qubit whereas the polarization state of an incident photon is a flying target qubit.Keywords
