Optically trapped, ultra-cold atoms provide a natural platform for quantum simulation and quantum computing. In this project, we use cold 87Rb atoms trapped in dynamic optical lattices to study many-body physics and to explore experimental quantum control of atom states.
Welcome to the Porto Research Group
Research on ultra-cold atoms lies at the intersection of atomic physics, many-body physics, quantum optics and quantum information. Quantum physics dominates the behavior of atomic gases cooled to near absolute zero temperature, and cold trapped atoms provide an ideal experimental system for studying quantum many-body physics. Our research focuses on ultra-cold gases of Rubidium atoms and Ytterbium/Rubidium mixtures, with the goals of studying novel condensed matter systems and engineering quantum control over many-body systems, including dissipative baths.
This is a new project, jointly led by Steve Rolston and Trey Porto, to use strong photon-photon interactions mediated by Rydberg atoms for quantum
Mixtures of ultracold atoms provide a range of opportunities for cold atom research beyond single-species experiments. In this project we plan to use mixtures of 87Rb and Yb atoms to study quantum gas mixtures.

We have recently observed interaction-induced broadening of a Rydberg transition in rubidium trapped in a 3D optical lattice.

Yang Wang has joined the Rb/Yb mixtures group! He comes to us as a recent Ph.D. from Dave Weiss' quantum computation group at Penn State, where he perfected addressable single qubit gates of neutral Cs atoms in a lattice.

Eric Magnon has joined the group! He comes to us as a joint graduate student between JQI/UMD and the Browaeys group at the Institute d'Optique. He will be working on the Rubidium Lattice experiment.

Elizabeth is moving on to a position at the Army Research Lab! Located near by, we hope to continue to have significant collaborations with her in her new position.

We have our first Bose-Einstein condensate after the move from NIST! Using an optical dipole trap plus a quadrupole magnetic trap, we were able to produce our first BEC on the UMD campus. The next step is to optimize the BEC and then get the optical lattice working.
