We will discuss a new type of interferometers that employ nonlinear devices as beam splitters. A specific scheme 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 will be discussed with topics including atom-light hybrid interferometer and simultaneous measurement of multiple orthogonal parameters.
16:30h get-together with coffee and snacks!
The seminar talk will be preceded by a CoQuS Student talk at 17:00h by Yijian Meng, TU Wien
