论文摘要
最近，一种新型的量子纠缠干涉仪采用了参数放大器作为波分裂和重组元件。量子纠缠源于参数放大器，该放大器产生量子相关场，用于探测干涉仪中的相变信号。这种类型的量子纠缠干涉仪表现出一些独特的特性，这些特性与传统的基于光束分离器的干涉仪（如马赫 - Zehnder干涉仪）不同。由于这些特性，它在许多方面都优于传统干涉仪，尤其是在相测量敏感性中。我们将回顾其在量子计量和传感，量子信息和量子状态工程方面的独特属性和应用。
A new type of quantum entangled interferometer was recently realized that employs parametric amplifiers as the wave splitting and recombination elements. The quantum entanglement stems from the parametric amplifiers, which produce quantum correlated fields for probing the phase change signal in the interferometer. This type of quantum entangled interferometer exhibits some unique properties that are different from traditional beam splitter-based interferometers such as Mach-Zehnder interferometers. Because of these properties, it is superior to the traditional interferometers in many aspects, especially in the phase measurement sensitivity. We will review its unique properties and applications in quantum metrology and sensing, quantum information, and quantum state engineering.
