Title: Choreographing Quantum Spin Dynamics with Light
Host: Erich Mueller
Abstract: 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 accessing 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 building and probing toy models of quantum gravity.
