Lorentz Boost下的量子纠缠

Quantum Entanglement under Lorentz Boost

Daeho Lee, Ee Chang-Young

摘要:

为了理解Lorentz助推下大质量粒子的量子纠缠特性,首先引入了一个相关的相对论自旋观测值,并计算了它在Lorentz助推下对Bell态的期望值.然后,我们表明,最大限度地违反贝尔不等式,可以通过适当地调整方向的自旋测量,即使在相对论运动的惯性系。由此我们推断,在Lorentz增强下,纠缠信息是以关联信息的形式保留下来的,这是由所使用的Bell态的变换特性决定的。

英文摘要:

In order to understand the characteristics of quantum entanglement of massive particles under Lorentz boost, we first introduce a relevant relativistic spin observable, and evaluate its expectation values for the Bell states under Lorentz boost. Then we show that maximal violation of the Bell's inequality can be achieved by properly adjusting the directions of the spin measurement even in a relativistically moving inertial frame. Based on this we infer that the entanglement information is preserved under Lorentz boost as a form of correlation information determined by the transformation characteristic of the Bell state in use.
