Using quantum smoothing for optical phase estimation

Thursday, March 11, 2010 - 09:21 in Physics & Chemistry

( -- "There are many situations where we need to measure the classical properties of a quantum system," Elanor Huntington tells "Optical phase estimation is one of these techniques, and it is central to applications where quantum beams of light are used, such as for gravitational wave detectors, quantum computing and quantum key distribution. Greater precision in measurements is important in this area, and that is what we have been working on."
