Physics Colloquium

The power of quantum information lies in its capacity to be non-local, encoded in correlations among entangled particles.  Yet our ability to produce, understand, and exploit such correlations is hampered by the fact that the interactions between particles are 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.  Advances in programming the form and graph of interactions with optical and magnetic fields are opening new opportunities in areas ranging from quantum technologies to fundamental physics.  I will touch on prospects in quantum-enhanced sensing, combinatorial optimization, and simulating toy models of quantum gravity.
