论文摘要
在宇宙中具有时间逆向不对称定律的不可逆性问题是物理学的核心问题。 ％，特别是统计力学，信息理论和量子热力学。在这封信中，我们首次讨论了最近提出的构造函数理论框架中如何出现不可逆性。在这里，不可逆性表示为任务是可能的，而其逆向则不是。特别是，我们证明了这种不可逆性与量子理论的时间逆转对称定律兼容，通过利用基于通用量子均匀的特定模型，用高质量的单光子码头实验实现了特定的模型。
The issue of irreversibility in a universe with time-reversal-symmetric laws is a central problem in physics. % , and, in particular, to statistical mechanics, information theory and quantum thermodynamics. In this letter, we discuss for the first time how irreversibility can emerge within the recently proposed constructor theory framework. Here irreversibility is expressed as the requirement that a task is possible, while its inverse is not. In particular, we demonstrate that this irreversibility is compatible with quantum theory's time reversal symmetric laws, by exploiting a specific model, based on the universal quantum homogeniser, realised experimentally with high-quality single-photon qubits.
