量子关联和经典关联的突变与Unruh效应

Sudden change in quantum and classical correlations and the Unruh effect

L. C. Celeri, A. G. S. Landulfo, R. M. Serra, G. E. A. Matsas

摘要:

我们使用Unruh效应来分析两个量子比特系统的经典和量子关联的动力学,当其中一个系统在有限的适当时间内均匀加速时。我们证明了在无限加速度的极限下,量子关联被完全破坏,而经典关联保持非零。特别是,我们表明,这种相关性表现出所谓的突然变化的行为作为加速度的函数。最后,我们讨论了当系统位于史瓦西黑洞的事件视界附近时,如何解释我们的结果。

英文摘要:

We use the Unruh effect to analyze the dynamics of classical and quantum correlations for a two-qubit system when one of them is uniformly accelerated for a finite amount of proper time. We show that the quantum correlation is completely destroyed in the limit of infinite acceleration, while the classical one remains nonzero. In particular, we show that such correlations exhibit the so-called sudden-change behavior as a function of acceleration. Eventually, we discuss how our results can be interpreted when the system lies in the vicinity of the event horizon of a Schwarzschild black hole.
