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…
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…
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…
