加速粒子的纠缠

Entanglement of Accelerating Particles

W. L. Ku, M. -C. Chu

摘要:

我们研究了当一对粒子中的一个或两个被均匀加速时,最大纠缠粒子对的纠缠是如何受到影响的,而探测器保持在惯性系中。我们发现,纠缠是不变的,如果考虑所有的自由度。然而,粒子对产生了,不同的二分系统的纠缠可能会随着加速度而改变。特别地,当加速度较大时,加速费米子之间的纠缠优先转移到所产生的反粒子,并且当加速度接近无穷大时,纠缠转移完成。然而,对于标量粒子,没有观察到纠缠转移到反粒子。

英文摘要:

We study how the entanglement of a maximally entangled pair of particles is affected when one or both of the pair are uniformly accelerated, while the detector remains in an inertial frame. We find that the entanglement is unchanged if all degrees of freedom are considered. However, particle pairs are produced, and the entanglements of different bipartite systems may change with the acceleration. In particular, the entanglement between accelerating fermions is transferred preferentially to the produced antiparticles when the acceleration is large, and the entanglement transfer is complete when the acceleration approaches infinity. However, for scalar particles, no entanglement transfer to the antiparticles is observed.
