论文摘要
在遥远的位置或电路的遥远节点之间建立钟声和格林伯格 - 霍恩林格状态的问题是一个困难且极为重要的问题，这是一种策略，该策略是纠缠的渗透率。我们提供了一种通过涉及在部分纠缠的纯双分部分纠缠状态的单层蜂窝晶格上的量子测量策略来实现末端的方法。然后，我们转到双层晶格，并在对局部量子操作的现实限制下，在该晶格上引入纠缠渗透，并在晶格节点上允许的经典通信。当应用于单层蜂窝晶格时，与通过现有方法获得相同现象相比，实际实现的策略将在实际实现中降低噪声效应。此外，对于双层蜂窝晶格，我们报告了在现实限制下的量子纠缠渗透的优势。
The problem of establishing Bell and Greenberger-Horne-Zeilinger states between faraway places or distant nodes of a circuit is a difficult and an extremely important one, and a strategy which addresses it is entanglement percolation. We provide a method for attaining the end through a quantum measurement strategy involving three-, two-, and single-qubit measurements on a single-layer honeycomb lattice of partially entangled pure bipartite entangled states. We then move over to a double-layered lattice, and introduce entanglement percolation on that lattice under a realistic restriction on local quantum operations and classical communication allowed on the nodes of the lattice. When applied to a single-layered honeycomb lattice, our strategy would call for less noise effects in an actual realization than when the same phenomenon is attained via existing methods. Moreover, for the double-layered honeycomb lattice, we report advantage of quantum entanglement percolation over classical entanglement percolation under the realistic restriction.
