Dynamics of quantum systems with long-range interactions

Location:Harvard Jefferson 250

Ten Minute Talk:"High-fidelity multi-qubit gates with neutral atoms" by Harry Levine

Atomic, molecular, and optical systems often exhibit long-range interactions, which decay with distance r as a power law 1/r^alpha. In this talk, we will derive bounds on how quickly quantum information can propagate in such systems. We will then discuss applications of these bounds to numerous phenomena including classical and quantum simulation of quantum systems, prethermal phases in Floquet systems, entanglement area laws, sampling complexity, and scrambling.
