同构分支上的量子对态传输

Quantum Pair State Transfer on Isomorphic Branches

Hiranmoy Pal, Sarojini Mohapatra

AI总结:

研究同构分支量子网络中对态传输特性,发现其演化仅依赖局部结构,且高保真顶点态传输图可作为同构分支实现高保真对态传输,还揭示了多种图中对态传输的存在性。

摘要:

在具有同构分支的量子网络中,由海森堡XY哈密顿量控制的特定对态演化仅取决于局部结构,即使全局结构改变也不受影响。所有能实现高保真顶点态传输的图,都可作为量子网络的同构分支以展现高保真对态传输。该结果用于揭示路径、环等多种图中对态传输的存在性。

英文摘要:

The evolution of certain pair state in a quantum network with isomorphic branches, governed by the Heisenberg $XY$ Hamiltonian, depends solely on the local structure, and it remains unaffected even if the global structure is altered. All graphs which enable high-fidelity vertex state transfer can be considered as isomorphic branches of a quantum network to exhibit high-fidelity pair state transfer. The results are used to unveil the existence of pair state transfer in various graphs, including paths, cycles, and others.
