Description
The discovery of gravitational waves (GW) from binary black holes and neutron stars has provided us with a stunning glimpse at an entirely new way to explore our Universe. In order to discover new phenomena and better understand the constituents of the Cosmos and the forces driving it, it is vital to improve the sensitivity of future GW observatories. Indeed it is necessary to go beyond the current quantum noise limit imposed by the uncertainty relation originating from a continuous position measurement of the interferometer mirrors. Quantum mechanics provides “speedmeters” (SM) as a more elegant approach: measuring speed of the test masses rather than position evades the uncertainty limit. The seminar will give an overview of the prospect of speed meter configurations, the technical challenges currently under investigations as well as an outlook on how speed meter technology can improve the EInstein Telescope sensitivity.
