Rydberg Atoms: Two’s Company, Three’s Still Company

Once relegated to the margins of atomic physics research as basically tunable microwave antennas (albeit with enviable success), highly excited “Rydberg” atomic states have experienced a resurgence of interest in the past decade at the hands of the quantum information community, owing to their giant polarizability and long natural lifetime.  In particular, the strong long-range...

Quantum Information Goes Splat on Causality's Windshield

Physicists sleep well at night comforted in the fact that information can’t travel faster than light, but determining where exactly the causality police write the speeding ticket in various systems can be tricky to pin down.  In an invited talk at QIM 2014, my colleague Paul Lett from NIST and the Joint Quantum Institute will present new measurements showing just how this speed limit...

5 Reasons We Can’t Wait for Quantum Information & Measurement (QIM) 2014

Greetings from Washington, DC, home of OSA headquarters, NIST, and the Joint Quantum Institute!  In less than two short months we’ll be converging on Berlin like a swarm of photon-hungry locusts for the 2014 Quantum Information and Measurement (QIM) meeting, the latest in the OSA’s conference series for all things quantum and measurable.  But ahead of that time, I...
