Query: Microwave--Optical entanglement in a Strongly Coupled
  Electro-Optomechanical System   Quantum transduction between microwave and optics can be realized by quantum
teleportation if given reliable microwave-optical entanglement, namely
entanglement-based quantum transduction. To realize this protocol, an entangled
source with high-fidelity between the two frequencies is necessary. In this
paper, we study the microwave and optical entanglement generation based on a
generic cavity electro-optomechanical system in the strong coupling regime.
Splittings are shown in the microwave and optical output spectra and the
frequency entanglement between the two modes is quantified. We show that
entanglement can be straightforwardly encoded in the frequency-bin degree of
freedom and propose a feasible experiment to verify entangled photon pairs. The
experimental implementation is systematically analyzed, and the preferable
parameter regime for entanglement verification is identified. An inequality is
given as a criterion for good entanglement verification with analysis of
practical imperfections.
