Entanglement and Decoherence of a Micromechanical Resonator via Coupling to a Cooper-Pair Box

Year: 2002

Type: article

Abstract: We analyze the quantum dynamics of a micromechanical resonator capacitively coupled to a Cooper-pair box. With appropriate quantum state control of the Cooper box, the resonator can be driven into a superposition of spatially separated states. The Cooper box can also be used to probe the decay of the resonator superposition state due to environmental decoherence.
