LIGO Breaks Quantum Boundaries

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has developed a new quantum technology called "squeezing" that allows it to surpass the quantum limit and measure undulations in spacetime across the entire range of gravitational frequencies. This breakthrough enables LIGO to probe a larger volume of the universe and is expected to detect about 60% more mergers than before, enhancing its ability to study exotic events that shake space and time. The technology has implications for future quantum technologies and fundamental physics experiments.
