立方体图上的量子网络

Quantum Networks on Cubelike Graphs

Anna Bernasconi, Chris Godsil, Simone Severini

摘要:

立方形图是初等阿贝尔群(Z_2)^n的凯莱图(例如,超立方体是立方形图)。本文给出了用一大类立方体图模拟的量子网络中两粒子间完全态转移的条件。这概括了Christandl等人[Phys. Rev. Lett. 92,187902(2004)]和Facer等人[Phys.Rev.A92,187902(2008)]。

英文摘要:

Cubelike graphs are the Cayley graphs of the elementary abelian group (Z_2)^n (e.g., the hypercube is a cubelike graph). We give conditions for perfect state transfer between two particles in quantum networks modeled by a large class of cubelike graphs. This generalizes results of Christandl et al. [Phys. Rev. Lett. 92, 187902 (2004)] and Facer et al. [Phys. Rev. A 92, 187902 (2008)].
