论文摘要
相关是量子信息处理和量子热力学的宝贵资源。但是，某些相关状态的制备可以承担应有的大量成本，应与其价值进行比较。我们表明，经典的相关性可以催化利用，从而可以减轻信息擦除中的热量和熵耗散。这些相关性是由擦除过程自然产生的，因此可以认为是免费的。尽管我们还表明，在理论上是可能的最大擦除且无相关性的最大擦除，但催化剂在预计会发生相关性的实际擦除设置中始终是有用的。
Correlations are a valuable resource for quantum information processing and quantum thermodynamics. However, the preparation of some correlated states can carry a substantial cost that should be compared against its value. We show that classical correlations can be catalytically exploited, which enables to mitigate heat and entropy dissipation in information erasure. These correlations are naturally generated by the erasure process, and thus can be considered free. Although we also show that maximum erasure with minimum dissipation and no correlations is theoretically possible, catalysts are always useful in practical erasure settings, where correlations are expected to take place.
