Manipulating Synchronous Optical Signals with a Double Atomic Ensemble
Zhuan Li, De-Zhong Cao, Kaige Wang
We analyze a double atomic configuration interacting with two signal beams and two control beams. Because of the quantum interference between the two channels, the four fie…
Experimental Observation of Classical Sub-Wavelength Interference with Thermal-Like Light
Jun Xiong, De-Zhong Cao, Feng Huang +3
We show the experimental observation of the classical sub-wavelength double-slit interference with a pseudo-thermal light source. The experimental results are in agreement with the…
Geometrical Optics in Coincidence Imaging System
De-Zhong Cao, Jun Xiong, Kaige Wang
We discuss the geometrical optics of coincidence imaging for two kinds of spatial correlations which are related to a classical thermal light source and a two-photon quantum entang…
Modularization of multi-qubit controlled phase gate and its NMR implementation
Jingfu Zhang, Wenzhang Liu, Zhiwei Deng +2
Quantum circuit network is a set of circuits that implements a certain computation task. Being at the center of the quantum circuit network, the multi-qubit controlled phase shift…
Nuclear Magnetic Resonance Implementation of a Quantum Clock Synchronization Algorithm
Jingfu Zhang, Guilu Long, Zhiwei Deng +2
The quantum clock synchronization algorithm proposed by I. L. Chuang (Phys. Rev. Lett, 85, 2006(2000)) has been implemented in a three qubit nuclear magnetic resonance quantum syst…
One-Photon and Two-Photon Double-Slit Interferences in Spontaneous and Stimulated Parametric Down-Conversions
De-Zhong Cao, Zhuan Li, Yan-Hua Zhai +1
We theoretically discuss one-photon and two-photon double-slit interferences for spontaneous and stimulated parametric down-conversions. We show that the two-photon sub-wavelength…
