Mechanical qubit-light entanglers in hybrid nonlinear qubit-optomechanics
arXiv:1906.02404 · doi:10.1103/PhysRevA.100.052310
Abstract
Interfacing between matter qubits and light is a crucial provision for numerous quantum technological applications. However, a generic qubit may not directly interact with a relevant optical field mode, and hence, one could necessitate to adjust frequencies to match resonance conditions between parties. In this work, we show how a parametric coupling of the qubit with a mechanical oscillator, in conjunction with the trilinear radiation pressure coupling of the same object with light, can induce maximal qubit-light entanglement at an optimal time. We also show how our method enables conditional nonclassical state preparation of an optical field state via qubit measurements in the weak optomechanical coupling regime, whereas nonclassical states of the same can dynamically be achieved in the moderate-to-strong single photon coupling limit. Our scheme benefits from not requiring any cooling of the mechanical component, and not needing an adjusting of the detunings and transition frequencies to have resonance between any pairs of quantum systems.
