Quantum Metrology with SU(1,1) Interferometers


We will discuss a new type of interferometers that employ nonlinear devices as beam splitters. A specific schmee with parametric amplifiers, the so called SU(1,1) interferometer, is implemented and is compared with a traditional linear interferometer. A new paradigm for quantum interferometry is found that is different from the noise reduction mechanism in squeezed state interferometry. Some applications of the new interferometer wil bee discussed with topics including atom-light hybrid interferometer and simultaneous measurement of multiple orthogonal parameters.
