Perfect function transfer and interference effects in interacting boson lattices

Lian-Ao Wu, Adam Miranowicz, XiangBin Wang, Yu-xi Liu, Franco Nori

摘要:

我们展示了如何完美地转移,没有状态初始化和远程合作,任意功能的相互作用玻色子格。我们描述了一种可能的实现状态转移通过玻色子原子捕获在光晶格或极化激元在片上耦合腔。值得注意的是,一个家庭的哈密顿量,线性和非线性的,发现这是相关的玻色-哈伯德模型,使任意函数的完美转移。结果表明,二维晶格中两个格点之间的态转移会由于不同路径中的中间格点数目不同而导致量子干涉。核物理中的签名因子可以用来描述这种量子干涉。

英文摘要:

We show how to perfectly transfer, without state initialization and remote collaboration, arbitrary functions in interacting boson lattices. We describe a possible implementation of state transfer through bosonic atoms trapped in optical lattices or polaritons in on-chip coupled cavities. Significantly, a family of Hamiltonians, both linear and nonlinear, is found which are related to the Bose-Hubbard model and that enable the perfect transfer of arbitrary functions. It is shown that the state transfer between two sites in two-dimensional lattices can result in quantum interference due to the different numbers of intermediate sites in different paths. The signature factor in nuclear physics can be useful to characterize this quantum interference.
