Quantum enhancement of long baseline gravitational wave detectors

该项目将设计和建造一个量子光学系统，当用于未来的长基线引力波探测器时，将提高其探测频段的灵敏度，从10赫兹到10千赫。本项目将在小型光学传感器上使用该系统来验证这一概念。在此过程中，它将首次使用压缩来降低量子辐射压力噪声。然后，该系统将准备好在Advanced LIGO的早期升级中部署，增加该探测器的科学产出，将引力波探测转变为引力波天文学。

This project will design and construct a quantum optical system which when used in future long baseline gravitational wave detectors will enhance sensitivity across their detection frequency band, from 10 Hz to 10 kHz. This project will use this system on small scale optical sensors to prove the concept. In so doing, it will use squeezing to reduce quantum radiation pressure noise for the first time. This system will then be ready for deployment on an early upgrade of Advanced LIGO increasing the science output of this detector, turning gravitational wave detection into gravitational wave astronomy.
