Entanglement, EPR correlations and mesoscopic quantum superposition by the high-gain quantum injected parametric amplification
摘要：
研究了单光子量子注入高增益光参量放大产生的多粒子量子叠加态和多粒子纠缠的持续性。采用基于最优普适量子克隆的物理结构，研究了当非线性参量增益g较大时，系统的纠缠和量子相干性是如何保持的.
英文摘要：
We investigate the multiparticle quantum superposition and the persistence of multipartite entanglement of the quantum superposition generated by the quantum injected high-gain optical parametric amplification of a single photon. The physical configuration based on the optimal universal quantum cloning has been adopted to investigate how the entanglement and the quantum coherence of the system persists for large values of the nonlinear parametric gain g.
