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…
Direct temporal mode measurement for the characterization of temporally multiplexed high dimensional quantum entanglement in continuous variables
Nan Huo, Yuhong Liu, Jiamin Li +6
Field-orthogonal temporal mode analysis of optical fields is recently developed for a new framework of quantum information science. But so far, the exact profiles of the temporal m…
Optimum quantum resource distribution for phase measurement and quantum information tapping in a dual-beam SU(1,1) interferometer
Yuhong Liu, Nan Huo, Jiamin Li +3
Quantum entanglement is a resource in quantum metrology that can be distributed to two orthogonal physical quantities for the enhancement of their joint measurement sensitivity, as…
Measuring the continuous variable quantum entanglement with a parametric amplifier assisted homodyne detection
Jiamin Li, Yuhong Liu, Nan Huo +4
Traditional method for measuring continuous-variable quantum entanglement relies on balanced homodyne detections, which are sensitive to vacuum quantum noise coupled in through los…
