Simultaneous multiple angular displacement estimation precision enhanced by the intramode correlation
Shoukang Chang, Wei Ye, Xuan Rao +5
The angular displacement estimation is one of significant branches of quantum parameter estimation. However, most of the studies have focused on the single-angular displacement est…
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…
Phase estimation of Mach-Zehnder interferometer via Laguerre excitation squeezed state
Zekun Zhao, Huan Zhang, Yibing Huang +1
Quantum metrology has an important role in the fields of quantum optics and quantum information processing. Here we introduce a kind of non-Gaussian state, Laguerre excitation sque…
Evaluating the quantum Ziv-Zakai bound in noisy environments
Shoukang Chang, Wei Ye, Xuan Rao +5
In the highly non-Gaussian regime, the quantum Ziv-Zakai bound (QZZB) provides a lower bound on the available precision, demonstrating the better performance compared with the quan…
