Optical interference by amplitude measurement
Yunxiao Zhang, Xuan Tang, Xueshi Guo +3
Interference effects are usually observed by intensity measurement. Path indistinguishability by quantum complementarity principle requires projection of the interfering fields int…
Full characterization of an all fiber source of heralded single photons
Yunxiao Zhang, Liang Cui, Xueshi Guo +3
We demonstrate a heralded single photon source which is based on the photon pairs generated from pulse pumped spontaneous four wave mixing in a piece of commercially available disp…
Multi-mode quantum correlation generated from an unbalanced SU(1,1) interferometer using ultra-short laser pulses as pump
Xueshi Guo, Wen Zhao, Xiaoying Li +1
Multi-mode entanglement is one of the critical resource in quantum information technology. Generating large scale multi-mode entanglement state by coherently combining time-delayed…
Temporal coherence of optical fields in the presence of entanglement
Yunxiao Zhang, Nan Huo, Liang Cui +5
In classical coherence theory, coherence time is typically related to the bandwidth of the optical field. Narrowing the bandwidth will result in the lengthening of the coherence ti…
General considerations in unbalanced fourth-order interference
Z. Y. Ou, Xiaoying Li
Interferometry has been used widely in sensing application. However, the technique is limited by the finite coherence time of the light sources when the interference paths are not…
Measurement-dependent erasure of distinguishability for the observation of interference in an unbalanced SU(1,1) interferometer
Nan Huo, Liang Cui, Yunxiao Zhang +4
It is known that quantum interference can disappear with the mere possibility of distinguishability without actually performing the act. We create such distinguishability in an unb…

We experimentally study a fiber-based three-stage nonlinear interferometer and demonstrate its application in generating heralded single photons with high efficiency and purity by…
Quantum enhanced joint measurement of multiple non-commuting observables with SU(1,1) interferometer
Yuhong Liu, Jiamin Li, Liang Cui +4
Heisenberg uncertainty relation in quantum mechanics sets the limit on the measurement precision of non-commuting observables, which prevents us from measuring them accurately at t…

Qian-Kun Gong, Dong Li, Chun-Hua Yuan +2
We theoretically present the quantum Cramér-Rao bounds (QCRB) of an SU(1,1) interferometer for Gaussian states input with and without the internal photonic losses. The phase shifts…
Effects of losses in the hybrid atom-light interferometer
Zhao-Dan Chen, Chun-Hua Yuan, Hong-Mei Ma +4
Enhanced Raman scattering can be obtained by injecting a seeded light field which is correlated with the initially prepared collective atomic excitation. This Raman amplification p…
Atom-light superposition oscillation and Ramsey-like atom-light interferometer
Cheng Qiu, Shuying Chen, L. Q. Chen +4
Coherent wave splitting is crucial in interferometers. Normally, the waves after this splitting are of the same type. But recent progress in interaction between atom and light has…

Xueshi Guo, Nannan Liu, Xiaoying Li +2
One of the important function in optical communication system is the distribution of information encoded in an optical beam. It is not a problem to accomplish this in a classical s…
