超越旋转波近似的精确纠缠动力学

Exact Entanglement Dynamics Beyond the Rotating Wave Approximation

S. M. Hashemi Rafsanjani, S. Agarwal, J. H. Eberly

摘要:

两个远程量子比特的纠缠动力学分析研究。量子比特与独立的谐振子在Jaynes-Cummings哈密顿量的理想化简并极限中任意强烈地相互作用。与众所周知的非简并RWA结果相反,研究表明理想简并量子位不能在其伙伴振子之间产生二分纠缠。

英文摘要:

The entanglement dynamics of two remote qubits is examined analytically. The qubits interact arbitrarily strongly with separate harmonic oscillators in the idealized degenerate limit of the Jaynes-Cummings Hamiltonian. In contrast to well known non-degenerate RWA results, it is shown that ideally degenerate qubits cannot induce bipartite entanglement between their partner oscillators.
