Quantum entangled Sagnac interferometer
Wen Zhao, Xuan Tang, Xueshi Guo +2
SU(1,1) interferometer (SUI) is a novel type of interferometer that uses directly entangled quantum fields for sensing phase change. For rotational sensing, Sagnac geometry is usua…

Time-domain measurement of ultra-fast intensity difference squeezed pulse pairs generated in fiber
Wen Zhao, Xueshi Guo, Xiaoying Li
Pulsed pumped four-wave mixing process via non-linearity in optical fiber can generate optical pulses with continuous variable quantum correlation. However, pair-wise cor…

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…
