Phase sensitivity approaching quantum Cramer-Rao bound in a modified SU(1,1) interferometer
Jian-Dong Zhang, Chenglong You, Chuang Li +1
SU(1,1) interferometers, based on the usage of nonlinear elements, are superior to passive interferometers in phase sensitivity. However, the SU(1,1) interferometer cannot make ful…
New kind of asymmetric integration projection operators constructed by entangled state representations and parity measurement
S. Wang, Z. P. Wang, J. D. Zhang
By means of the technique of integration within an ordered product of operators and Dirac notation, we introduce a new kind of asymmetric integration projection operators in entang…
Classical Inputs and Measurements Enable Phase Sensitivity beyond the Shot-Noise Limit
Jian-Dong Zhang, Zi-Jing Zhang, Long-Zhu Cen +2
Coherent-state-based phase estimation is a fruitful testbed for the field of precision measurements since coherent states are robust to decoherence when compared with exotic quantu…
