Abstract

We demonstrate the generation of high-quality entangled photon pairs in the 1310-nm O-band. Using an ultra-stable source design, we produce polarization entanglement with 97.5% fidelity as characterized via coincidence basis tomography.

Drop-in compatible entanglement for optical-fiber networks

Matthew Hall, Joseph B. Altepeter, Prem Kumar

A growing number of quantum communication protocols require entanglement distribution among remote parties, which is best accomplished by exploiting the mature technology and extensive infrastructure of low-loss optical fiber. For this reason, a practical source of entangled photons must be drop-in compatible with optical fiber networks. Here we demonstrate such a source for the first time, in which the nonlinearity of standard single-mode fiber is utilized to yield entangled photon pairs in the 1310-nm O-band. Using an ultra-stable design, we produce polarization entanglement with 98.0% +/- 0.5% fidelity to a maximally entangled state as characterized via coincidence-basis tomography. To demonstrate the source's drop-in capability, we transmit one photon from each entangled pair through a telecommunications-grade optical amplifier set to boost classical 1550-nm (C-band) communication signals. We verify that the photon pairs experience no measurable decoherence upon passing through the active amplifier (the output state's fidelity with a maximally entangled state is 98.4% +/- 1.4%).

High quality telecom-band polarization-entangled photon-pairs from a stable, pulse-pumped, short PPLN waveguide

Han Chuen Lim, Akio Yoshizawa, Hidemi Tsuchida +1 more

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.

We demonstrate a novel alignment-free all-fiber source for generating telecom-band polarization-entangled photon pairs. Up to 91.7% two-photon-interference visibility is observed without subtracting accidental coincidences arising from background photons while operating the source at room temperature.

Fiber based entangled photon-pair source

Xiaoying Li, Jun Chen, Kim Fook Lee +3 more

We present a fiber based source of entangled photon-pairs in the 1550 nm telecom band that can be integrated into the existing fiber network and is well suited for quantum information processing. With this source we have demonstrated the generation, storage, and long-distance distribution of polarization entanglement in standard optical fiber. We have also investigated the origin of the large number of accidental coincidences in the experiments, which has been proved to be Raman scattering, and discussed how to suppress the Raman scattering to improve the quality of the fiber source.
