A microwave scattering spectral method to detect the nanomechanical vibrations embedded in a superconducting qubit
Haiyan Gao, Lianfu Wei
Nanomechanical resonators (NMRs), as the quantum mechanical sensing probers, have played the important roles for various high-precision quantum measurements. Differing from the pre…
Generalized Bell-like inequality and maximum violation for multiparticle entangled Schrödinger-cat-states of spin-s
Yan Gu, Wei-Dong Li, Xiao-Lei Hao +2
This paper proposes a generalized Bell-like inequality (GBI) for multiparticle entangled Schrödinger-cat--states of arbitrary spin-. Based on quantum probability statistics the…
Maximum violation of Wigner inequality for two-spin entangled states with parallel and antiparallel polarizations
Yan Gu, Haifeng Zhang, Zhigang Song +2
The experimental test of Bell's inequality is mainly focused on Clauser-Horne-Shimony-Holt (CHSH) form, which provides a quantitative bound, while little attention has been pained…
Single-atom polarizer
W. A. Li, L. F. Wei
Traditional polarizer provides a way to convert an unknown polarization into a specified polarization. According to Malus, the intensity of the transmission is directly proportiona…
Stark-chirped rapid adiabatic passage in the presence of dissipation for quantum computation
X. Shi, C. H. Oh, L. F. Wei
Stark-chirped rapid adiabatic passage (SCRAP) is an important technique used for coherent quantum controls. In this paper we investigate how the practically-existing dissipation of…
Quantum computation with surface-state electrons by rapid population passages
X. Shi, L. F. Wei, C. H. Oh
Quantum computation requires coherently controlling the evolutions of qubits. Usually, these manipulations are implemented by precisely designing the durations (such as the -pul…
Controllable entanglement preparations between atoms in spatially-separated cavities via quantum Zeno dynamics
Wen-An Li, L. F. Wei
By using quantum Zeno dynamics, we propose a controllable approach to deterministically generate tripartite GHZ states for three atoms trapped in spatially separated cavities. The…
Quantum nondemolition measurements of a flux qubit coupled to a noisy detector
Wei Jiang, Yang Yu, Lianfu Wei
We theoretically study the measurement-induced dephasing caused by back action noise in quantum nondemolition measurements of a superconducting flux qubit which is coupled to a sup…
Frequency-doubled scattering of symmetry-breaking surface-state electrons on liquid Helium
Miao Zhang, Wenzhi Jia, Lianfu Wei
Any systems with symmetry-breaking eigenstates can effectively radiate photons with doubled frequency of the incident light, which is known as the second harmonic generation. Here,…
