Bell inequality of frequency-bin entangled photon pairs with time-resolved detection
Xianxin Guo, Yefeng Mei, Shengwang Du
Entanglement, describing the inseparability of a quantum multiparty system, is one of the most intriguing features of quantum mechanics. Violation of Bell inequality, for ruling ou…
Frequency-Bin Entanglement with Tunable Phase
Xianxin Guo, Peng Chen, Chi Shu +2
We describe a technique to produce narrow-band photon pairs with frequency-bin entanglement, whose relative phase can be tuned using linear polarization optics. We show that, makin…
Narrowband Biphotons with Polarization-Frequency Coupled Hyperentanglement
Chi Shu, Xianxin Guo, Peng Chen +2
We demonstrate the generation of narrowband biphotons with polarization-frequency coupled hy- perentanglement from spontaneous four-wave mixing in cold atoms. The coupling between…
Temporal Quantum-State Tomography of Narrowband Biphotons
Peng Chen, Chi Shu, Xianxin Guo +2
We describe and demonstrate a quantum state tomography for measuring the complex temporal waveform of narrowband biphotons. Through six sets of two-photon interference measurements…
