"Breaking Boundaries: LIGO Shatters Quantum Limit"

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has developed a new quantum technology called "frequency-dependent squeezing" that allows it to surpass the limits imposed by quantum physics and make more precise measurements of gravitational waves. By manipulating light in different ways depending on the frequency of the waves, LIGO can reduce quantum noise and improve its sensitivity across the entire range of gravitational frequencies. This breakthrough technology is expected to increase LIGO's ability to detect mergers between black holes and neutron stars by about 60 percent, opening up new possibilities for studying exotic cosmic events. The advancements in squeezing also have implications for future quantum technologies and fundamental physics experiments.
