Nonclassical properties of Hermite polynomial's excitation on squeezed vacuum and its decoherence in phase-sensitive reservoirs
Shi-You Liu, Ya-Zhou Li, Li-Yun Hu +3
We introduce Hermite polynomial excitation squeezed vacuum (SV) H_{n}(O)S(r)|0> with O=u a+v a^{+}. We investigate analytically the nonclassical properties according to Mandel's Q…

Jun Li, Dawei Lu, Zhihuang Luo +3
Precisely characterizing and controlling realistic open quantum systems is one of the most challenging and exciting frontiers in quantum sciences and technologies. In this Letter,…
Nonperturbative Leakage Elimination Operators and Control of a Three-Level System
Jun Jing, Lian-Ao Wu, Mark Byrd +3
Dynamical decoupling operations have been shown to reduce errors in quantum information processing. Leakage from an encoded subspace to the rest of the system space is a particular…
An ideal experiment to determine the 'past of a particle' in the nested Mach-Zehnder Interferometer
Fu Li, F. A. Hashmi, Jun-Xiang Zhang +1
An ideal experiment is designed to determine the past of a particle in the nested Mach-Zehnder interferometer (MZI) by using standard quantum mechanics with quantum non-demolition…
Application of the weak-measurement technique to study atom-vacuum interactions
M. Zhang, S. Y. Zhu
Quantum weak measurement has attracted much interest recently [J. Dressel et al., Rev. Mod. Phys. 86, 307 (2014)] because it could amplify some weak signals and provide a technique…
Post-selected von Neumann measurement with Hermite-Gaussian and Laguerre-Gaussian pointer states
Yusuf Turek, Hirokazu Kobayashi, Tomotada Akutsu +2
Through the von Neumann interaction followed by post-selection, we can extract not only the eigenvalue of an observable of the measured system but also the weak value. In this post…
Probing the non-locality of Majorana fermions via quantum correlations
Jun Li, Ting Yu, Hai-Qing Lin +1
Majorana fermions (MFs) are exotic particles that are their own anti-particles. Recently, the search for the MFs occurring as quasi-particle excitations in solid-state systems has…
Microwave degenerate parametric down-conversion with a single cyclic three-level system in circuit QED
Z. H. Wang, C. P. Sun, Yong Li
With the assistance of a single cyclic three-level system, which can be realized by a superconducting flux qubit, we study theoretically the degenerate microwave parametric down-co…
Multiple phase estimation for arbitrary pure states under white noise
Yao Yao, Li Ge, Xing Xiao +2
In any realistic quantum metrology scenarios, the ultimate precision in the estimation of parameters is limited not only by the so-called Heisenberg scaling, but also the environme…
Distribution of quantum Fisher information in asymmetric cloning machines
Xing Xiao, Yao Yao, Lei-Ming Zhou +1
An unknown quantum state cannot be copied on demand and broadcast freely due to the famous no-cloning theorem. Approximate cloning schemes have been proposed to achieve the optimal…

Z. H. Wang, Y. J. Ji, Yong Li +1
The longitudinal coupling of a system to the bath usually induces the pure dephasing of the system. In this paper, we study the collective dephasing induced dissipation and decoher…
