源靶解纠缠与Laser量子态
Disentanglement of Source and Target and the Laser Quantum State
摘要：
提出了激光源与其目标量子比特的解纠缠作为确定激光量子态为相干态的判据。结果表明，当忽略环境记录监测激光泵浦量子时，源靶密度算符在相干态下具有唯一的因式分解。然而，以完整的环境记录为条件的源-目标状态是纠缠的，作为已知总量子数的状态（源加目标）。
英文摘要：
Disentanglement of a laser source from its target qubit is proposed as a criterion establishing the laser quantum state as a coherent state. It is shown that the source-target density operator has a unique factorization in coherent states when the environmental record monitoring laser pump quanta is ignored. The source-target state conditioned upon the complete environmental record is entangled, though, as a state of known total quanta number (source plus target).
