Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

Scientists have seen "spooky" quantum behaviour happening to objects at the human scale, according to a new paper. Researchers have seen quantum fluctuations "kick" large objects such as mirrors, ...

As one of the key experimentalists to conceptualize and then build one of the biggest experiments in history, Nobel-prize-winning physicist Rainer Weiss’s path to success is remarkable. Now aged 90 he ...

Squeezed state-of-the-art: LIGO team members install equipment as part of the squeezed-light upgrade. (Courtesy: LIGO/Caltech/MIT/Matt Heintze) Quantum squeezing has been used to increase the ...

Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...

LIGO Hanford has a new partner in its search for gravitational waves created by violent events in space. Scientists are expecting the expanded network to lead to more detections of ripples through ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

An international team of scientists today announced what could be the biggest breakthrough in physics in a hundred years. Specifically, they claim to have at last detected gravitational waves, the ...

The journey began about 20 years ago. The Laser Interferometer Gravitational Wave Observatory (LIGO) was built in Handford, Washington, and Livingston, Louisiana, to detect and study the gravitational ...

Detector engineers Hugh Radkins (foreground) and Betsy Weaver (background) take up positions inside the vacuum system of the detector at LIGO Hanford Observatory to perform the hardware upgrades ...
