Quantum enhancement of gravitational wave astronomy

该项目旨在设计、建造和测试一种长波长的“压缩真空”源，将整个音频频段的量子噪声降低10倍以上，并具有长期的稳定性和可靠性。这种量子技术是LIGO旅行者号引力波探测器计划改进的三个关键领域之一。该项目将提高引力波天文学和宇宙学的灵敏度和覆盖范围，提高引力波观测的保真度和覆盖范围。所开发的技术可以应用于精密测量和引力波观测等其他领域。

The project aims to design, build and test a long wavelength ‘squeezed vacuum’ source reducing quantum noise by more than a factor of 10 across the audio frequency band with long term stability and reliability. This quantum technology is one of three key areas of improvement planned for the gravitational wave detector, LIGO Voyager. The project will enhance the sensitivity and the reach of gravitational wave astronomy and cosmology, and improve the fidelity and reach of gravitational wave observations. Technologies developed may find application in other areas of precision measurements and gravitational wave observations .
