及时监控系统信息广播过程

Monitoring of the process of system information broadcasting in time

Piotr Mironowicz, Jarosław Korbicz, Paweł Horodecki

摘要:

现代物理学的基本问题之一是经典世界、热力学第二定律和整个不可逆性如何从可逆演化的量子现实中出现。这涉及到测量转换量子的问题,不可复制的数据,对主体间的,可复制的经典知识。我们利用量子态的鉴别,在一个中心系统模型中展示了它的演化如何导致经典信息的传播。我们分析了正交化和退相干的过程,它们的时间尺度和对环境的依赖性。

英文摘要:

One of the fundamental problems of modern physics is how the classical world, the 2nd Law of Thermodynamics and the whole irreversibility emerges from the quantum reality with reversible evolution. This relates to the problem of measurement transforming quantum, non-copyable data, towards intersubjective, copyable classical knowledge. We use the quantum state discrimination to show in a central system model how it's evolution leads to the broadcasting of the classical information. We analyze the process of orthogonalization and decoherence, their time scales and dependence on the environment.
