Quantum optics: Kittens catch phase
Jonathan P. Dowling1
Abstract
The most sensitive phase-measuring instrument yet uses quantum trickery and a scaled-down version of the notorious Schrödinger's cat. It means that more sensitive devices for metrology and imaging could be on the way.
Elsewhere in this issue, a group of Australian researchers (Higgins et al., page 393)1 reports the construction of the most sensitive optical interferometer yet. At the heart of this success lies a cunning use of quantum feedback to minimize photon phase noise in the device — a technique that could have applications in imaging, remote sensing, gravity-wave detection and spectroscopy.
