Topic: 
Choreographing Quantum Spin Dynamics with Light

Venue: 
Hewlett 200
Speaker: 
Prof. Monika Schleier-Smith (Stanford)
Abstract / Description: 

The power of quantum information lies in its capacity to be non-local, encoded in correlations among two, three, or many entangled particles. Yet our ability to produce, understand, and exploit such correlations is hampered by the fact that the interactions between particles and ordinarily local. I will report on experiments in which we use light to induce long-range interactions among cold atoms, with photons acting either as messengers or as a means of coupling to highly polarizable Rydberg states. The combination of optically programmable interactions with imaging of spin dynamics opens new opportunities in areas ranging from quantum-enhanced sensing to quantum simulation. As an illustrative example, I will touch on prospects for building and probing toy models for information scrambling in black holes.
