论文摘要
我们研究了单个光子在一维有限的Glauber-fock腔阵列中的转移，该腔阵列的耦合强度满足了平方根定律。如果腔是谐振剂，则可以将阵列中进化的状态映射到上部截短的连贯状态。共振频率的适当选择可以在阵列中的任意两个腔之间进行完美的传递。光子的完美传递允许在腔之间进行完美的量子状态转移。我们的发现可能有助于实现光子晶格中的量子通信和信息处理。
We study transfer of single photon in an one-dimensional finite Glauber-Fock cavity array whose coupling strengths satisfy a square root law. The evolved state in the array can be mapped to an upper truncated coherent state if the cavities are resonant. Appropriate choices of resonance frequencies provide perfect transfer of a photon between any two cavities in the array. Perfect transfer of the photon allows perfect quantum state transfer between the cavities. Our findings may help in realizing quantum communication and information processing in photonic lattices.
