Ancilla-Assisted Generation of Photons from Vacuum via Time-Modulation of Extracavity Qubit
We propose a scheme for the generation of photons from a vacuum via time-modulation of a quantum system indirectly coupled to the cavity field through some ancilla quantum subsystem. We consider the simplest case when the modulation is applied to an artificial two-level atom (we call ‘t-qubit’, that...
