Dissipation-based entanglement via quantum Zeno dynamics and Rydberg antiblockade
arXiv:1705.03614 · doi:10.1103/PhysRevA.95.062339
Abstract
A novel scheme is proposed for dissipative generation of maximally entanglement between two Rydberg atoms in the context of cavity QED. The spontaneous emission of atoms combined with quantum Zeno dynamics and Rydberg antiblockade guarantees a unique steady solution of the master equation of system, which just corresponds to the antisymmetric Bell state . The convergence rate is accelerated by the ground-state blockade mechanism of Rydberg atoms. Meanwhile the effect of cavity decay is suppressed by the Zeno requirement, leading to a steady-state fidelity about as the single-atom cooperativity parameter , and this restriction is further relaxed to once the quantum-jump-based feedback control is exploited.
