Quantum computing … atomic physics … entanglement?

My research uses the tools of atomic physics to push the state-of-the-art in quantum computing.  We have blurred the line between physics and information theory.  In my work, I have implemented several ways of storing information in single trapped atoms, and then used the interactions of light and matter to manipulate that information in ways that defy classical physics.

In my Ph.D. work I built a 2D grid of single cesium atom qubits, the largest fully addressable quantum computer at the time.  Following that, in my post-doc at the Joint Quantum Institute I built a quantum networking system of trapped barium and ytterbium ion qubits.  Using entanglement and “spooky action at a distance” these ion qubits form a small quantum network.

I love teaching and looking forward to sharing my love of physics with Bates students this year in PHYS 107, 222 and 301!  I run a quantum computing journal club which meets (and eats) every Tuesday 4:30-5:30 in Commons 225.  Students of any level or background are welcome and invited to this journal club, which is in spirit a language course designed to introduce you to the vernacular of this exciting and rapidly emerging field.  The club will be of interest to students of Physics, Computational Studies (DCS), Math, and more!

In my spare time, I am a competitive speed skater, and have even given talks on the physics of speed skating.

I am looking for research students of all years.  If you are interested in my research, the quantum computing journal club, or chatting about speed skating, please e-mail me or stop by Carnegie 333.

Office hours for Winter 2020: Tuesdays 3-4pm, Wednesdays 1-5pm, Thursdays 9:30am-10:50am, or e-mail me to set up another time.
