论文摘要
量子转导是指微波和光学状态之间的相干转换，如果给出量子传送，则可以通过量子传送，如果给出了高富达微波炉 - 光学纠缠，即基于纠缠的量子转导。可以使用各种平台生成可靠的微波纠缠。在本文中，我们基于对压电的机电系统的讨论，并使传送诱导的转化方案在量子通道理论的框架中更具体。通过比较基于纠缠的转换通道与传统的直接量子转导通道之间的量子能力，我们显示基于纠缠的方案确实可以在直接量子转导量零量子能力为零时承认正面转导率。给定两个压电机电系统，我们还研究了从连续变量和离散可变设置中纠缠交换的微波微波纠缠的产生，显示了通过微波微波微波量子量子直接连接微波量子处理器的潜力。
Quantum transduction refers to the coherent conversion between microwave and optical states, which can be achieved by quantum teleportation if given high fidelity microwave-optical entanglement, namely entanglement-based quantum transduction. Reliable microwave-optical entanglement can be generated using various platforms. In this paper, we base the discussion on piezo-optomechanical system and make the teleportation induced conversion scheme more concrete in the framework of quantum channel theory. By comparing the quantum capacity between the entanglement-based conversion channel and the traditional direct quantum transduction channel, we show entanglement-based scheme indeed admits a positive transduction rate when the direct quantum transduction has zero quantum capacity. Given two piezo-optomechanical systems, we also investigate the generation of microwave-microwave entanglement from entanglement swapping within continuous variable and discrete variable settings, showing the potentials of directly connecting microwave quantum processor by microwave-microwave quantum teleportation.
