Query: Optomechanical transducers for quantum information processing   We discuss the implementation of optical quantum networks where the interface
between stationary and photonic qubits is realized by optomechanical
transducers [K. Stannigel et al., PRL 105, 220501 (2010)]. This approach does
not rely on the optical properties of the qubit and thereby enables optical
quantum communication applications for a wide range of solid-state spin- and
charge-based systems. We present an effective description of such networks for
many qubits and give a derivation of a state transfer protocol for
long-distance quantum communication. We also describe how to mediate local
on-chip interactions by means of the optomechanical transducers that can be
used for entangling gates. We finally discuss experimental systems for the
realization of our proposal.
