标题： Quantum-state transfer in staggered coupled-cavity arrays

摘要： 我们研究了一个耦合腔阵列，其中每个腔与原子相互作用，并在旋转波近似下进行分析。 对于交错的腔间耦合模式，会出现一对场正常模，每个都局域在阵列的两端。 因此，可以根据原子和场模式之间的共振条件来探讨丰富的动力学阶段结构。 我们证明了这可以用来实现高保真的光子、原子或极化子态的量子态转移（QST）。 此外，通过将阵列划分为更短的小模块组，可以在不影响保真度的情况下显著缩短QST时间。 显示英文摘要

摘要： We consider a coupled-cavity array, where each cavity interacts with an atom under the rotating-wave approximation. For a staggered pattern of inter-cavity couplings, a pair of field normal modes each bi-localized at the two array ends arise. A rich structure of dynamical regimes can hence be addressed depending on which resonance condition between the atom and field modes is set. We show that this can be harnessed to carry out high-fidelity quantum-state transfer (QST) of photonic, atomic or polaritonic states. Moreover, by partitioning the array into coupled modules of smaller length, the QST time can be substantially shortened without significantly affecting the fidelity.
