Quantum computation with mesoscopic superposition states
arXiv:quant-ph/0001018 · doi:10.1103/PhysRevA.61.042309
Abstract
We present a strategy to engineer a simple cavity-QED two-bit universal quantum gate using mesoscopic distinct quantum superposition states. The dissipative effect on decoherence and amplitude damping of the quantum bits are analyzed and the critical parameters are presented.
