Stark-tuned Forster resonances in Rydberg atoms and their application for quantum information
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Dr. Ilya Beterov, Institute of Semiconductor Physics Novosibirsk, Russia
Abstract: We present results of theoretical and experimental studies of Stark-tuned Forster resonances in Rydberg atoms. Two trapped<br>
atoms are excited into Rydberg states which are then tuned by the external electric field midway between two other Rydberg states of the opposite parity. The collective two-atom states are coupled by dipole-dipole interaction. We have proposed schemes of two-qubit gates using adiabatic passage of Forster resonances in time-dependent electric field. We have shown that radiofrequency electric fields can induce additional "inaccessible" resonances which are useful both for coherent coupling and for adiabatic passage. We have experimentally observed Borromean three-body Forster resonances for three interacting Rydberg atoms.
