三格点光晶格中费米子-费米子散射的耗散动力学

Dissipative Dynamics Of Fermion-Fermion Scattering In A Three-Site Optical Lattice

Vladimir P. Villegas, Roland Cristopher F. Caballar

摘要:

在这篇文章中,我们研究了暴露在费米环境中的三位光晶格中费米气体的耗散动力学。晶格位置允许最多一个自旋向上和一个自旋向下的粒子在同一时间和它与费米环境的相互作用,导致粒子被捕获或驱逐出it. It然后表明,除了每个晶格位置被至少一个粒子填充,观察到自旋交换,这使得该系统被用来加密信息通过量子密码学的可能性。此外,我们还观察到晶格点之间的纠缠,表明在这种超冷原子系统中粒子之间传输量子信息是可能的。

英文摘要:

In this article, we investigate the dissipative dynamics of a Fermi gas trapped in a three-site optical lattice exposed to a fermionic environment. The lattice sites admit at most one spin-up and one spin-down particle at a time and its interaction with the fermionic environment cause particles to either be trapped by or expelled from it. It is then shown that apart from each lattice site being populated by at least one particle, spin exchange is observed, which allows the possibility for the system to be used to encrypt information via quantum cryptography. Furthermore, we also observe entanglement among the lattice sites, denoting that transport of quantum information among particles is possible in this ultracold atomic system.
