Quantum multiparameter estimation with multi-mode photon catalysis entangled squeezed state
Huan Zhang, Wei Ye, Shoukang Chang +3
We propose a method to generate the multi-mode entangled catalysis squeezed vacuum states (MECSVS) by embedding the cross-Kerr nonlinear medium into the Mach-Zehnder interferometer…

Quantum-improved phase estimation with a displacement-assisted SU(1,1) interferometer
W. Ye, S. K. Chang, S. Y. Gao +3
By performing two local displacement operations (LDOs) inside an SU(1,1) interferometer, called as the displacement-assisted SU(1,1) [DSU(1,1)], both the phase sensitivity based on…
