    The Laser Interferometer Gravitational-Wave Observatory (LIGO) has improved its detection of cosmic events by overcoming quantum noise through advanced “squeezing” technology. This breakthrough will increase its detection rate by 60 percent and pave the way for advancements in quantum technology and physics. Researchers using LIGO achieved a landmark in quantum squeezing. In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, made history when it made the first direct detection of gravitational waves, or ripples in space and time, produced by a pair of colliding black holes. Since then, the U.S. National Science Foundation (NSF)-funded LIGO and its sister detector in...
