- R. G. Herb Condensed Matter Seminar
- Quantum gates and simulations with Rydberg atoms in a lattice
- Time: 3:00 pm - 4:00 pm
- Place: 5310 Chamberlin
- Speaker: David Petrosyan, Institute of Electronic Structure and Laser, FORTH, Heraklion, Crete, Greece
- Abstract: Atoms in highly excited Rydberg states posses unique properties, including long lifetimes and large dipole moments. Laser excitation of atoms to the Rydberg states then provides a well controlled mechanism for switchable interatomic interactions, which has been widely used to realize quantum gates and quantum simulations with cold atoms in arrays of microtraps. I will discuss some of our recent research on these topics. In particular, I will describe the energy spectrum and microscopic dynamics of transitions to spatially-ordered states in finite-size chains of atoms realizing the quantum Ising model. I will then show how these results can be used to implement quantum gates between distant atoms in a lattice mediated by a Rydberg excitation antiferromagnet.

- Astronomy Colloquium
- Colloquium Show and Tell
- Time: 3:30 pm - 4:30 pm
- Place: 4421 Sterling Hall
- Abstract: The first two colloquia on September 5th and September 12th will be our annual department orientation (also known as the "show and tell"). During these sessions, everyone will have 1.5 minutes to introduce themselves and provide a brief overview of their work. This is a wonderful opportunity for us all to get to know each other better and learn about the diverse research happening within our department.
