Description
Quantum measurement of the motion of particles originated in the study of gravitational-wave detectors. One part of the talk will motivate why and how further acceleration in our ability to measure motion can shed light on the nature of gravity. I will then describe the recent unconditional observation of quantum back-action on gravitational-wave detectors, realizing one of the long-standing theoretical predictions in quantum measurement theory. The second half of the talk will describe quantum enhancement in the measurement of waveforms and in generating clock signals, all of which expand the toolset at the frontier of quantum measurement science.
