Multiple electromagnetically induced transparency without a control field in an atomic array coupled to a waveguide
W. Z. Jia, Q. Y. Cai
We investigate multiple electromagnetically induced transparency (EIT) in a waveguide quantum electrodynamics (wQED) system containing an atom array. By analyzing the effective Ham…
Improving the performance of twin-field quantum key distribution with advantage distillation technology
Hong-Wei Li, Rui-Qiang Wang, Chun-Mei Zhang +1
In this work, we apply the advantage distillation method to improve the performance of a practical twin-field quantum key distribution system under collective attack. Compared with…
Coherent single-photon scattering spectra for a giant-atom waveguide-QED system beyond dipole approximation
Q. Y. Cai, W. Z. Jia
We investigate the single-photon scattering spectra of a giant atom coupled to a one dimensional waveguide via multiple connection points or a continuous coupling region. Using a f…
Wheeler-DeWitt equation rejects quantum effects of grown-up universes as a candidate for dark energy
Dongshan He, Qing-yu Cai
In this paper, we study the changes of quantum effects of a growing universe by using Wheeler-DeWitt equation (WDWE) together with de Broglie-Bohm quantum trajectory approach. From…
High fidelity quantum cloning of two known nonorthogonal quantum states via weak measurement
Ming-Hao Wang, Qing-Yu Cai
We propose a scheme to enhance the fidelity of symmetric quantum cloning machine using a weak measurement. By adjusting the intensity of weak measurement parameter , we obtain t…
Hidden Messenger from Quantum Geometry: Towards Information Conservation in Quantum Gravity
Xiao-Kan Guo, Qing-yu Cai
The back reactions of Hawking radiation allow nontrivial correlations between consecutive Hawking quanta, which gives a possible way of resolving the paradox of black hole informat…
