摘要： 基于腔光机械系统实现光子-光子之间的量子隐形传态已经取得了重要进展, 但将便于传输的光子量子态通过量子隐形传态传输到长寿命的声子上, 仍然是一个亟待解决且富有挑战的问题。本文基于混合腔光机械系统, 提出通过非线性相互作用, 实现固态量子比特和飞行量子比特之间的未知量子态非局域传输的物理实现方案。为探索该方案的实验可行性, 重点考虑了环境温度和腔的耗散对保真度的影响。结果表明, 在一定的温度和耗散条件下, 通过调节适当的参数, 可以实现高保真度的声子-光子之间的混合量子隐形传态, 该结果对非局域混合量子信息处理具有一定的理论意义。

Abstract: The realization of photon-photon quantum teleportation based on cavity optomechanical system has made important progress. Nevertheless, transmitting the photon's quantum state that are convenient for transmission to phonon with long lifetime via quantum teleportation is still an challenging issue that awaits resolution. Based on the hybrid cavity optomechanical system, a physical implementation scheme for the nonlocal transmission of unknown quantum states solid-state qubits and flying qubits through nonlinear interaction is proposed. In order to explore the feasibility of the scheme, the influence of temperature and cavity dissipation on the fidelity of hybrid quantum teleportation between phonon and photon is considered. The results show that high-fidelity hybrid quantum teleportation between phonon and photon can be realized by adjusting appropriate parameters under certain temperature and dissipation conditions, which has high theoretical significance in non-local hybrid quantum information processing.
