Abstract

We demonstrate an ultra-stable, pulse-pumped source of telecom-band polarization-entangled photon-pairs using 1-mm-long PPLN waveguide placed in a polarization-diversity fiber-loop without temperature control. Full tomographic characterization confirms a purity higher than 0.94 and fidelity exceeding 0.96.

Stable source of high quality telecom-band polarization-entangled photon-pairs based on a single, pulse-pumped, short PPLN waveguide

We demonstrate a stable source of high quality telecom-band polarization-entangled photon-pairs based on a single, pulse-pumped, short periodically-poled lithium niobate (PPLN) waveguide. Full quantum state tomographic measurement performed on the photon-pairs has revealed a very high state purity of 0.94, and an entanglement fidelity exceeding 0.96 at the low-rate-regime. At higher rates, entanglement quality degrades due to emission of multiple-pairs. Using a new model, we have confirmed that the observed degradation is largely due to double- and triple-pair emissions.

CW-laser-pumped telecom-band polarization-entangled photon-pair source with a fidelity of 97.8%

Yinghong Xue, Akio Yoshizawa, Hidemi Tsuchida

Quantum entanglement is one of the most important resources for quantum communication, information and computing. Since active polarization stabilization methods could alleviate the polarization-drift problem over optical fibre, telecom-band polarization-entangled photon-pairs can be well distributed and shared. Spontaneous four-wave mixing in a dispersion-shifted fibre (DSF) can be used to realize a source of telecom-band polarization-entangled photon pairs, but DSF is often cooled to suppress noise photons generated by spontaneous Raman-scattering. Second-order nonlinear crystals or waveguides such as periodically-poled lithium niobate (PPLN) waveguides are also available and generation has been reported on the conditions of careful selection of two nearly identical nonlinear crystals or accurate temperature-control of waveguides.

Ultra stable all-fiber telecom-band entangled photon-pair source for turnkey quantum communication applications

Chuang Liang, Kim Fook Lee, Todd Levin +2 more

We demonstrate a novel alignment-free all-fiber source for generating telecom-band polarization-entangled photon pairs. Polarization entanglement is created by injecting two relatively delayed, orthogonally polarized pump pulses into a piece of dispersion-shifted fiber, where each one independently engages in four-photon scattering, and then removing any distinguishability between the correlated photon-pairs produced by each pulse at the fiber output. Our scheme uses a Michelson-interferometer configuration with Faraday mirrors to achieve practically desirable features such as ultra-stable performance and turnkey operation. Up to 91.7% two-photon-interference visibility is observed without subtracting the accidental coincidences that arise from background photons while operating the source at room temperature.

Integrable optical-fiber source of polarization-entangled photon pairs in the telecom band

Xiaoying Li, Chuang Liang, Kim Fook Lee +3 more

We demonstrate an optical-fiber-based source of polarization-entangled photon pairs with improved quality and efficiency, which has been integrated with off-the-shelf telecom components and is, therefore, well suited for quantum communication applications in the 1550-nm telecom band. Polarization entanglement is produced by simultaneously pumping a loop of standard dispersion-shifted fiber with two orthogonally polarized pump pulses, one propagating in the clockwise and the other in the counterclockwise direction. We characterize this source by investigating two-photon interference between the generated signal-idler photon pairs under various conditions. The experimental parameters are carefully optimized to maximize the generated photon-pair correlation and to minimize contamination of the entangled photon pairs from extraneously scattered background photons that are produced by the pump pulses for two reasons: (i) spontaneous Raman scattering causes uncorrelated photons to be emitted in the signal and idler bands and (ii) broadening of the pump-pulse spectrum due to self-phase modulation causes pump photons to leak into the signal and idler bands. We obtain two-photon interference with visibility $>90%$ without subtracting counts caused by the background photons (only dark counts of the detectors are subtracted), when the mean photon number in the signal (idler) channel is about 0.02/pulse, while no interference is observed in direct detection of either the signal or idler photons.
