The method of Squeezing, more precise detection of collisions of stellar-mass black holes in the Universe

23 October 2019

The 'quantum squeezers' designed at ANU along with other upgrades for the current LIGO detectors have already greatly improved the detectors’ sensing capabilities in the third detection run that resumed in April 2019.

CGP’s newest publication ‘Broadband reduction of quantum radiation pressure noise via squeezed light injection’ elaborates on the method of ‘Squeezing’. Published in Nature Photonics in Oct 2019, this method dampens quantum noise and makes measurements more precise, critical for next-generation detectors, which are expected to come online within the next 20 years.
