Quantum super-resolution for imaging two pointlike entangled photon sources
Huan Zhang, Wei Ye, Ying Xia +2
We investigate the resolution for imaging two pointlike entangled sources by using the method of the moments and the spatial-mode demultiplexing (SPADE), where the pointlike entang…
Global quantum thermometry based on the optimal biased bound
Shoukang Chang, Wei Ye, Xuan Rao +6
Thermometry is a fundamental parameter estimation problem which is crucial in the development process of natural sciences. One way to solve this problem is to the extensive used lo…
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…
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…
Improvement of phase sensitivity in SU(1,1) interferometer via a Kerr nonlinear
Shoukang Chang, Wei Ye, Huan Zhang +3
We propose a theoretical scheme to enhance the phase sensitivity by introducing a Kerr nonlinear phase shift into the traditional SU(1,1) interferometer with a coherent state input…
