标题： Dephasing induced long-ranged entangled pairs

摘要： 这项工作提出了一种去相位机制，用于在晶格中生成对称定位的长程纠缠对。我们考虑了一个一维费米子晶格，该晶格具有最近邻跃迁，并且在中心位置受到局部去相位的影响。在强对称性下，由去相位引起的动力学表现出强烈的松弛特性，并在不同的对称性子空间中产生独特的稳态。通过显式的解析计算，我们确定了支持这些强关联鲁棒对的对称性子空间，这些对称性子空间能够在任意长的距离上保持稳定，并提供了稳态相关矩阵的解析表达式。这项具有实验相关性的研究有望在新兴量子技术中得到应用。 显示英文摘要

摘要： This work proposes a dephasing mechanism for generating symmetrically located long-range entangled pairs in a lattice. We consider a one-dimensional fermionic lattice with nearest-neighbor hopping subjected to a local dephasing at the central site. The dephasing-induced dynamics is strongly relaxing under strong symmetries and give rise to unique steady states in different symmetry sectors. Through explicit analytical calculations, we identify the symmetry sectors that support these strongly correlated robust pairs over arbitrarily long distances and provide analytical expressions of the steady-state correlation matrices. This experimentally relevant work promises applications in emerging quantum technologies.
