Optical single photons on-demand teleported from microwave cavities

We propose a scheme for entangling the optical and microwave output modes of the respective cavities by using a micro mechanical resonator. The micro mechanical resonator, on one side, is capacitively coupled to the microwave cavity and, on the other side, it is coupled to a high-finesses optical cavity. We then show how this continuous variable entanglement can be profitably used to teleport the non-Gaussian number state |1> and the superposition (|0> + |1>)/sqrt(2) from the microwave cavity output mode onto an output of the optical cavity mode with fidelity much larger than the no-cloning limit.
