光晶格中玻色-爱因斯坦凝聚体的简并四波混频产生和探测原子纠缠

Atomic entanglement generation and detection via degenerate four-wave-mixing of a Bose-Einstein condensate in an optical lattice

摘要:

明确检测两个不同物质波脉冲之间的纠缠是一个重大挑战,尚未得到实验证明。我们描述了一个现实的方案,以产生和检测两个原子物质波脉冲之间的连续变量纠缠通过简并四波混频从最初捕获的玻色-爱因斯坦凝聚体加载到一个一维光晶格。我们进行了全面的数值研究固定凝聚参数,以确定最大违反的可分性和Einstein-Podolsky-Rosen不等式场正交纠缠,并描述和模拟的实验方案,测量必要的正交。

英文摘要:

The unequivocal detection of entanglement between two distinct matter-wave pulses is a significant challenge that has yet to be experimentally demonstrated. We describe a realistic scheme to generate and detect continuous variable entanglement between two atomic matter-wave pulses produced via degenerate four-wave-mixing from an initially trapped Bose-Einstein condensate loaded into a one-dimensional optical lattice. We perform a comprehensive numerical investigation for fixed condensate parameters to determine the maximum violation of separability and Einstein-Podolsky-Rosen inequalities for field quadrature entanglement, and describe and simulate an experimental scheme for measuring the necessary quadratures.
