  We examine the entanglement properties of a system that represents two driven
microwave cavities each optomechanically coupled to two separate driven optical
cavities which are connected by a single-mode optical fiber. The results
suggest that it may be possible to achieve near-maximal entanglement of the
microwave cavities, thus allowing a teleportation scheme to enable interactions
for hybrid quantum computing of superconducting qubits with optical
interconnects.
