非惯性系中的量子退相干

Quantum decoherence in noninertial frames

Jieci Wang, Jiliang Jing

摘要:

量子退相干是指系统与环境发生不可逆相互作用时产生的一种现象,它在描述量子到经典跃迁中起着重要作用,并已成功地应用于一些重要的实验中。本文首次研究了非惯性系中的退相干。结果表明,退相干和由Unruh效应产生的纠缠损失之间存在着显著的相互影响。有趣的是,在退相干下的整个系统的情况下,纠缠的突然死亡可能会出现任何加速。然而,在只有Rob量子位经历退相干的情况下,只有当加速度参数大于“临界点”时,才会发生突然死亡。"

英文摘要:

Quantum decoherence, which appears when a system interacts with its environment in an irreversible way, plays a fundamental role in the description of quantum-to-classical transitions and has been successfully applied in some important experiments. Here, we study the decoherence in noninertial frames for the first time. It is shown that the decoherence and loss of the entanglement generated by the Unruh effect will influence each other remarkably. It is interesting to note that in the case of the total system under decoherence, the sudden death of entanglement may appear for any acceleration. However, in the case of only Rob's qubit underging decoherence sudden death may only occur when the acceleration parameter is greater than a "critical point."
