Quantum non-demolition measurement based on an SU(1,1)-SU(2)-concatenated atom-light hybrid interferometer
文献摘要：
Quantum non-demolition(QND)measurement is an important tool in the fields of quantum information processing and quantum optics.The atom-light hybrid interferometer is of great interest due to its combination of an atomic spin wave and an optical wave,which can be utilized for photon number QND measurement via the AC-Stark effect.In this paper,we present an SU(l,l)-SU(2)-concatenated atom-light hybrid interferometer,and theoretically study QND measurement of the photon number.Compared to the traditional SU(2)interferometer,the signal-to-noise ratio in a balanced case is improved by a gain factor of the nonlinear Raman process(NRP)in this proposed interferometer.Furthermore,the condition of high-quality QND measurement is analyzed.In the presence of losses,the measurement quality is reduced.We can adjust the gain parameter of the NRP in the readout stage to reduce the impact due to losses.Moreover,this scheme is a multiarm interferometer,which has the potential of multiparameter estimation with many important applications in the detection of vector fields,quantum imaging,and so on.
