报告摘要：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. Furthermore, the nonlinear process allows the coupling of different types of waves and leads to hybrid interferometry involving different waves. Some specific atom-light hybrid interferometers will be discussed.
