熵的贝尔不等式是否隐含在第二定律中?

Are entropic Bell inequalities implied by the second law?

Ian T. Durham

摘要:

贝尔不等式,在塞尔夫和阿达米给出的形式,来自热力学第二定律和马尔可夫假设的组合。违反这些不等式讨论的混合特性的密度算子。一个量子力学约束的系统的三个量子比特,其中两个纠缠,被发现,并示出在一种情况下,导致强次加性。最后,在解释的结果中,不确定性关系在熵的定义和第二定律中发挥的作用进行了讨论,展示了贝尔不等式的链接。此外,第二定律被证明是依赖于量子系统中的测量类型。具体来说,第二定律的一个更一般的陈述,适用于量子和经典系统的建议。

英文摘要:

Bell's inequalities, in the form given by Cerf and Adami, are derived from the combination of the second law of thermodynamics and the Markov postulate. Violations of these inequalities are discussed in terms of the mixing characteristics of the density operators. A quantum mechanical bound for a system of three qubits, two of which are entangled, is found and is shown to lead to strong subadditivity in one case. Finally, in interpreting the results, the role the uncertainty relations play in the definition of entropy and the second law is discussed, demonstrating a link to Bell's inequalities. Additionally the second law is shown to be dependent on the type of measurement in quantum systems. Specifically, a more general statement of the second law appropriate to both quantum and classical systems is suggested.
