论文摘要
强电场中的Schwinger工艺会产生纠缠的颗粒和反颗粒。发现颗粒和反粒子之间的纠缠熵等于所产生系统的统计吉布斯熵。在这里，我们研究了电脉冲序列中量子干扰的影响，并表明量子干扰抑制了创建的量子状态的纠缠熵。这可能与量子增强的古典通信有关。我们的结果可以扩展到各种两级量子系统。
The Schwinger process in strong electric fields creates particles and antiparticles that are entangled. The entropy of entanglement between particles and antiparticles has been found to be equal to the statistical Gibbs entropy of the produced system. Here we study the effect of quantum interference in sequences of electric pulses, and show that quantum interference suppresses the entanglement entropy of the created quantum state. This is potentially relevant to quantum-enhanced classical communications. Our results can be extended to a wide variety of two-level quantum systems.
