摘要:

被囚禁的中性原子为复杂量子系统的鲁棒模拟提供了一条强有力的途径。本文提出了一种利用$n$ -体相互作用在可寻址光晶格中捕获的中性原子上实现哈密顿量的频闪方案,该方案仅使用1-体和2-体物理操作以及允许热化到有限温度或冷却到基态的耗散机制.我们证明了这一计划与应用程序的复曲面代码哈密顿量,基态的耦合到低温水库时,可以用来鲁棒地存储量子信息。

英文摘要:

Trapped neutral atoms offer a powerful route to robust simulation of complex quantum systems. We present here a stroboscopic scheme for realization of a Hamiltonian with $n$-body interactions on a set of neutral atoms trapped in an addressable optical lattice, using only 1- and 2-body physical operations together with a dissipative mechanism that allows thermalization to finite temperature or cooling to the ground state. We demonstrate this scheme with application to the toric code Hamiltonian, ground states of which can be used to robustly store quantum information when coupled to a low temperature reservoir.
