Characterizing Topological Phase Transition in Non-Hermitian Systems
ZhaoXiang Fang, Yongxu Fu, Guang-Can Guo +1
We propose and present a concept of Topological Distance (TD), obtained from the integration of trace distance over the generalized Brillouin zone, in order to characterize the top…
Heralded quantum memory for single-photon polarization qubits
G. W. Lin, X. B. Zou, X. M. Lin +1
We propose a scheme to implement a heralded quantum memory for single-photon polarization qubits with a single atom trapped in an optical cavity. In this scheme, an injected photon…
Experimental demonstration of phase measurement precision beating standard quantum limit by projection measurement
F. W. Sun, B. H. Liu, Y. X. Gong +3
We propose and demonstrate experimentally a projection scheme to measure the quantum phase with a precision beating the standard quantum limit. The initial input state is a twin Fo…
A Hybrid Quantum Encoding Algorithm of Vector Quantization for Image Compression
Chao-Yang Pang, Zheng-Wei Zhou, Guang-Can Guo
Many classical encoding algorithms of Vector Quantization (VQ) of image compression that can obtain global optimal solution have computational complexity O(N). A pure quantum VQ en…
Quantum memory for individual polarization photon
G. P. Guo, G. C. Guo
Here we present an experimentally feasible quantum memory for individual polarization photon with long-lived atomic ensembles excitations. Based a process similar to teleportation,…
