Subnatural-linewidth biphotons from a Doppler-broadened hot atomic vapor cell
Chi Shu, Peng Chen, Tsz Kiu Aaron Chow +4
We report the efficient generation of subnatural-linewidth (< 6 MHz, for Rb D1/D2 lines) biphotons from a Doppler-broadened (530 MHz) hot atomic vapor cell. We use on-resonance spo…
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…
Optimal Storage and Retrieval of Single-Photon Waveforms
Shuyu Zhou, Shanchao Zhang, Chang Liu +5
We report an experimental demonstration of optimal storage and retrieval of heralded single-photon wave packets using electromagnetically induced transparency (EIT) in cold atoms a…
