Quantum nonlinear optics with single photons enabled by strongly interacting atoms

We have realized a quantum nonlinear medium that transmits one, but absorbs two photons. This is accomplished by coupling slowly traveling photons in an atomic gas to highly excited, strongly interacting Rydberg states. This result opens not only possibilities for single-photon sources, but may also enable deterministic quantum gates between photons.

Institute of Theoretical Atomic, Molecular and Optical Physics (ITAMP) accepting applications for 2012 postdoctoral fellowship appointment

Investment in high-power fiber laser technology for industrial processing and military applications has enabled commercial lasers with hundreds of Watts of diffraction-limited output to come to market. These lasers are ideal pump sources for high-power (10s to 100s of Watts), widely tunable optical parametric oscillators which may be tuned from the visible to the mid-infrared...

Markus Greiner named MacArthur Foundation fellow

The 19th ICOLS conference takes place June 8-12 in Hokkaido, Japan, with CUA representation. Vladan Vuletic will report on a joint MIT-Harvard CUA experiment with Mikhail Lukin on switching of light with light using pulses containing only a few hundred photons. For a readable explanation of how to make light interact with light see the...
