Entangling Narrowband Photon Pairs

Abstract

We review our recent progress in generating and manipulating narrowband (∼ MHz) entangled pahoton pairs from spontaneous four-wave mixing in atomic ensembles. These photons are ideal for interacting with atomic nodes in a photon-atom quantum network.

Generation of Narrowband Hyperentangled Biphotons

We generate narrowband hyperentangled nondegenerate paired photons using spontaneous four-wave mixing in cold atoms. The entanglement in both time-frequency and polarization is confirmed by correlation measurements and quantum state tomography.

Generation and modulation of narrow-band photon pairs in cold atomic ensembles

Shiliang Zhu

Narrow-band entangled photon pairs could not only provide powerful tools to test some basic concepts of quantum mechanics,e.g.,nonlocal property,but also be used to improve long-distance quantum communication and scalable distributed linear optical quantum computation.The authors reviewed the experimental aspects of the generation and modulation of such kind of narrow-band entangled photon pairs in cold atoms through spontaneous four wave mixing and electromagnetic induced transparency.

Subnatural-Linewidth Polarization-Entangled Photon Pairs with Controllable Temporal Length

Kai-Yu Liao, Hui Yan, J. He +3 more

We demonstrate an efficient experimental scheme for producing polarization-entangled photon pairs from spontaneous four-wave mixing (SFWM) in a laser-cooled (85)Rb atomic ensemble, with a bandwidth (as low as 0.8 MHz) much narrower than the rubidium atomic natural linewidth. By stabilizing the relative phase between the two SFWM paths in a Mach-Zehnder interferometer configuration, we are able to produce all four Bell states. These subnatural-linewidth photon pairs with polarization entanglement are ideal quantum information carriers for connecting remote atomic quantum nodes via efficient light-matter interaction in a photon-atom quantum network.

Narrowband photon pair generation and waveform reshaping

J. F. Chen, Shengwang Du

In this article, we review on narrowband photon pairs produced in nonlinear crystals, and especially in atomic ensembles. In atomic ensembles, “write-read” process in pulse mode and spontaneous four-wave mixing process (SFWM) in continuous mode are two popular photon pair generation schemes. We specifically discuss the experimental works with continuous SFWM scheme in cold atomic ensembles. Photon pairs produced in these systems are characteristic of controllable long coherence time, and therefore are accessible with direct temporal modulation. We elaborate on the recent techniques on modulation and waveform reshaping of narrow-band paired photons.
