两个同时加速观测者的量子关联的变化

Change of quantum correlation for two simultaneously accelerated observers

Yue Li, Yongjie Pan, Baocheng Zhang

摘要:

研究了当一个或两个观测者被加速时,Unruh效应对量子纠缠态的量子关联和经典关联的影响。结果表明,当只有一个观测者被加速时,量子关联和经典关联会随着加速度的增加而趋近于一个有限值,而当两个观测者被加速时,量子关联和经典关联会迅速减小到零.后一个结果意味着当加速度是由引力场引起时,引力场会明显地破坏相关性。因此,当两个观测者处于引力场中时,量子关联或经典关联不容易长期保持。

英文摘要:

The influence of Unruh effect on the quantum and classical correlation of a quantum entangled state is investigated, when one or two of the observers are accelerated. It is found that the quantum and classical correlation would approach to a finite value with the increase of the acceleration when only one observer is accelerated, but they would decrease to zero quickly when two observers are accelerated. The latter result implies that the gravitational field would break the correlation obviously when the acceleration is caused by the gravitational field. Thus, when the two observers stay in the gravitational field, the quantum or classical correlation would not easy to be preserved for a long time.
