Kevin Jones: Article Describes Production of Interesting Quantum State of Light

Posted Dec. 6, 2011: Kevin Jones, William Edward McElfresh Professor of Physics, working with colleagues at the National Institute of Standards and Technology, published an article in Optics Express titled “Multi-spatial-mode single-beam quadrature squeezed states of light from four-wave mixing in hot rubidium vapor.” Optics Express is a peer reviewed, rapid publication, open access journal more »

Frederick W. Strauch: "Ultraefficient Cooling of Resonators: Beating Sidebar Cooling with Quantum Control"

Posted Nov. 14, 2011: Assistant Professor of Physics Frederick W. Strauch, in collaboration with Kurt Jacobs and colleagues at the University of Massachusetts Boston, published a paper describing a new theoretical approach to cooling quantum systems. This work showed that by applying ideas of quantum control one could cool the vibration modes of small oscillators more »

Kevin Jones: Grant to Support Summer Students

Posted May 6, 2011: The National Institute of Standards and Technology, through its Summer Undergraduate Fellowship Program (NIST-SURF), has awarded Williams College a grant to support summer research by David Kealhofer and Christina Knapp, both current sophomores. The students will be working at NIST in Gaithersburg MD doing research on advanced quantum optics with NIST more »

Frederick Strauch: Publishes Paper "Parallel State Transfer and Efficient Quantum Routing on Quantum Networks"

Posted Jan. 3, 2011: Frederick Strauch, Assistant Professor of Physics, and Chris Chudzicki ’10 published a paper describing a new theoretical analysis of the routing of information in quantum networks.  Inspired by recent experiments on superconducting circuits, they discovered that certain networks of quantum oscillators can be used to route entanglement robustly and with optimal more »

Kevin Jones: Publishes on Quantum Information Technology

Posted July 1: Kevin Jones, McElfresh Professor of Physics, in collaboration with colleagues at the National Institute of Standards and Technology, published a paper describing a laboratory realization of a near-ideal amplifier for light and a study of its effects on the quantum mechanical state of a pair of light beams.  The article,  “Low-noise amplification more »

Kevin Jones: Research appears in Optics Express, leading peer reviewed journal

Dec. 9: Kevin Jones, McElfresh Professor of Physics, working with colleagues at the National Institute of Standards and Technology, published a paper describing a technique for producing light beams whose fluctuations are more highly correlated than those produced by any classical optics technique.  Such light sources are of potential interest for quantum communication and quantum more »
