利用Aharonov-Casher效应检验Leggett不等式

Testing Leggett's Inequality Using Aharonov-Casher Effect

摘要:

Bell不等式是建立在局部实在论基础上的。量子力学对贝尔不等式的违反意味着定域性或实在论或两者都是站不住脚的。Leggett不等式是基于非局部实在论导出的。莱格特不等式的违反意味着量子力学既不是定域实在论,也不是非定域实在论。非定域实在论与量子力学的不相容性已被光子实验所证实。在我们的工作中,我们建议使用Aharonov-Casher效应来测试Leggett不等式。在我们的方案中,从两个源发射的四个纠缠粒子表现出两个量子比特类型的关联,这可能导致违反Leggett不等式,同时满足类空分离的无信号条件。我们的计划是宽容的一些地方的不准确性,由于拓扑性质的Aharonov-Casher阶段。我们的方案的实验实施可能通过钙原子偏振干涉仪实验来实现。

英文摘要:

Bell's inequality is established based on local realism. The violation of Bell's inequality by quantum mechanics implies either locality or realism or both are untenable. Leggett's inequality is derived based on nonlocal realism. The violation of Leggett's inequality implies that quantum mechanics is neither local realistic nor nonlocal realistic. The incompatibility of nonlocal realism and quantum mechanics has been urrently confirmed by photon experiments. In our work, we propose to test Leggett's inequality using the Aharonov-Casher effect. In our scheme, four entangled particles emitted from two sources manifest a two-qubit-typed correlation that may result in the violation of the Leggett inequality, while satisfying the no-signaling condition for spacelike separation. Our scheme is tolerant to some local inaccuracies due to the topological nature of the Aharonov-Casher phase. The experimental implementation of our scheme can be possibly realized by a calcium atomic polarization interferometer experiment.
