Macroscopic quantum mechanics in gravitational-wave observatories and beyond

15 March 2022

Recent observations on the GW observatories LIGO and Virgo showed that the quantum uncertainty of intense laser light affected the quantum uncertainty of 40 kg mirrors. We review these observations and provide links to fundamental physical research.

Overcoming the Challenges of Quantum Decoherence in Ultra-Precise Sensing

Quantum decoherence has long been a significant barrier to achieving the highest levels of sensitivity in ultra-precise force sensors. In our latest experiment, we discovered that generating quantum squeezed light directly within the sensor can substantially mitigate the effects of decoherence...
