Quantum enhanced high frequency gravitational wave searches — •Tom Krokotsch1, Lars Fischer1, and Gudrid Moortgat-Pick1,2 — 1Universität Hamburg, Hamburg, Germany — 2Deutsches Elektronen Synchrotron DESY, Hamburg, Germany
A promising way to probe physics beyond the Standard Model is to search for gravitational wave (GW) signals at high frequencies where known astrophysical sources can not obscure the signal. Similar to the search for dark matter, microwave cavity resonators can be used to detect faint effects from GWs. This talk will focus on the possibility to apply quantum enhancement techniques like vacuum squeezing to operate such detectors beyond the standard quantum limit. In particular, we will highlight the unique benefit this would bring to transient GW sensitivities such as those for primordial black hole mergers.
