Event Description

The sensitivity of advanced gravitational-wave is limited by Standard Quantum Limit. To surpass this detection limit, methods for a broadband suppression of quantum noise is necessary. In this talk, after a brief introduction about quantum noise physics in gravitational wave detectors, we will show that this task can be done by exploiting Einsteinâ€“Podolskyâ€“Rosen-entangled light. Harnessing their mutual quantum correlations and the difference in the way each beam propagates in the interferometer, the quantum noise can be engineered in a required manner. Our proposal is appropriate for all future gravitational-wave detectors for achieving sensitivities beyond the standard quantum limit.
