Abstract

We report our progress towards the realization of a tunable and narrow-band source of correlated photons for coherent manipulation of cold atoms, using a combination of four-wave mixing and electromagnetically induced transparency.

Coherence time limit of entangled paired photons generated in a cold atom cloud

Through electromagnetically-induced transparency (EIT) assisted spontaneous four-wave mixing, we produce the entangled paired photons with a coherence time of 2.34 μs from a cold atom cloud. The EIT dephasing rate is the ultimate limit.

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.

We report the first experimental demonstration of four-wave mixing using electromagnetically induced transparency in cold atoms. Backward-wave, phase-matched difference-frequency conversion is achieved at optical powers of a few nanowatts and at energies of less than a picojoule.

Generation of biphotons with long correlation time in cold atoms

Luwei Zhao

Driven by the desire of narrow-band photon pairs source, in this Mphil thesis work, we demonstrate the generation of photon pairs with controllable coherence time up to 1.72 microseconds, using spontaneous four-wave mixing with electromagnetically induced transparency in a laser-cooled atomic ensemble with an optical depth (OD) as high as 130. At such a high OD, we find that the pump laser intensity profile has a significant effect on the time-frequency entangled two-photon waveform. We also confirm the quantum particle nature of heralded narrow-band single photons generated from this source.
