We report a polarization-entangled photon-pair source obtained via spontaneous four-wave
mixing (SFWM) in a Doppler-broadened atomic ensemble of R 87 b atoms using a Sagnac …

Quantum information is often carried in the frequency and polarization degrees of freedom
(DoFs) in single photons and entangled photons. We demonstrate an approach to couple …

We experimentally demonstrate a scheme for the preparation of high-dimensional
hyperentangled photon pairs with path degree of freedom (DOF) and orbital-angular …

Bragg reflection waveguides emitting broadband parametric downconversion (PDC) have
been proven to be well suited for the on-chip generation of polarization entanglement in a …

The realization of a narrowband photonic quantum source based on an atomic device is
considered essential in the practical development of photonic quantum information science …

We present a phase-stable and selectable repetition-rate (f rep) divider (PSRD) of an optical
frequency comb (OFC) by down-picking a train of pulses from the fundamental OFC phase …

Photonic quantum states generated from atomic systems play prominent roles in long-
distance quantum networks and scalable quantum communication, because entangled …

We investigate the spectral–temporal biphoton waveforms of the photon pairs emitted from
cascade-type two-photon-coherent warm 87Rb atoms via the spontaneous four-wave mixing …

The ability to generate biphoton state with tunable properties in various degrees of freedom
(DoFs) is always a challenging task in the field of quantum information processing. This …

Abstract Since early 1990s, Mach–Zehnder interferometer has been used to investigate the
interference of biphoton wave packets. Due to subpicosecond time coherence of biphoton …
