论文摘要
可以在量子信息争夺中寻求信息悖论的可能解决方案。在此范式中,据推测,进入黑洞的所有信息均快速且混乱地分布在整个事件范围内,因此无法通过任何局部测量来重建信息。但是,在这种情况下,通常会忽略破坏性的影响,这可能会在宇宙学环境中引起信息。在这项工作中,我们开发了关键步骤,朝着对开放量子系统中信息争夺的热力学描述。特别是,我们将熵的生产分为争夺和腐烂引起的贡献,为此我们得出了第二定律的陈述。这是对Sachdev-Ye-Kitaev,Maldacena-QI,XXX,混合场ISING,Lipkin-Meshkov-Glick模型在能量或计算基础上有折叠的情况下进行的数字研究的补充。
A possible solution of the information paradox can be sought in quantum information scrambling. In this paradigm, it is postulated that all information entering a black hole is rapidly and chaotically distributed across the event horizon making it impossible to reconstruct the information by means of any local measurement. However, in this scenario the effects of decoherence are typically ignored, which may render information scrambling moot in cosmological settings. In this work, we develop key steps towards a thermodynamic description of information scrambling in open quantum systems. In particular, we separate the entropy production into contributions arising from scrambling and decoherence, for which we derive statements of the second law. This is complemented with a numerical study of the Sachdev-Ye-Kitaev, Maldacena-Qi, XXX, mixed field Ising, Lipkin-Meshkov-Glick models in the presence of decoherence in energy or computational basis.
