论文摘要
量子转导是扩展分布式量子体系结构的重要组成部分，并根据各种物理平台积极追求。但是，证明具有正量子能力的传感器实际上仍然具有挑战性。在这项工作中，我们讨论了一种新的方法，以放大阻抗匹配条件到一半阻抗匹配条件，这是通过在电磁换能器中引入两光驱动来实现的。我们显示可以增强量子转导能力，并可以在Bloch-Messiah分解的帮助下在简单的干扰图中理解。确定了具有正量子能力的参数状态，并在有没有驱动器的情况下进行比较，这表明参数驱动器诱导的增强确实有望证明量子状态转换，并且有望通过各种物理平台提高转导性能。
Quantum transduction is an essential ingredient in scaling up distributed quantum architecture and is actively pursued based on various physical platforms. However, demonstrating a transducer with positive quantum capacity is still practically challenging. In this work, we discuss a new approach to relax the impedance matching condition to half impedance matching condition, which is achieved by introducing two-photon drive in the electro-optic transducer. We show the quantum transduction capacity can be enhanced and can be understood in a simple interference picture with the help of Bloch-Messiah decomposition. The parameter regimes with positive quantum capacity is identified and compared with and without the drive, indicating that the parametric drive-induced enhancement is really promising in demonstrating quantum state conversion, and is expected to boost the performance of transduction with various physical platforms.
