- Long range interactions between Rydberg atoms
- Time: 4:00 pm
- Place: 2241 Chamberlin Hall
- Speaker: Saffman, University of Wisconsin-Madison
- Abstract: Interactions between Rydberg states of neutral atoms are a promising approach for fast and long range quantum gates. We have demonstrated that a single Rydberg excited Rb atom blocks excitation of a second atom located more than 10 microns away. The observed probability of double excitation of < 20% is consistent with a theoretical model of the Rydberg interaction. Progress towards using blockade to demonstrate a quantum CNOT gate with neutral atoms as well as ideas for creating multiqubit entanglement will be presented.
