Deep in the basement of the Varian Physics Lab in the Engineering Quad is an atom interferometer, an experimental apparatus that could hold the key to confirming Einstein’s century-old prediction of ...

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of ...

A heterodyne interferometry system with a fiber-optic sensor was developed to measure the temperature history of unburned gas in an engine cylinder. A polarization-preserving fiber and metal mirror ...

New research reveals that Apple is looking at how to make Siri detect particular voices, and also determine their location, solely through vibrations. Two newly-revealed patent applications show that ...
