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…
