Novel quantum dynamics with superconducting qubits — •Pedram Roushan — Google Quantum, Santa Barbara, CA, USA

In recent years superconducting qubits have become one of the leading platforms for quantum computation and simulation. We utilize these Noisy Intermediate Scale Quantum (NISQ) processors to study nonequilibrium quantum dynamics and simulate quantum phases of matter. I will present some of our recent works in studying robustness of bound states of photons [1], measurement-induced quantum information phases [2], braiding of non-Abelian anyons [3], and the universality classes of dynamics in the 1D Heisenberg chain [4]. Time permitting, I will talk about our effort on analog simulation, using the native Hamiltonian of the device. A goal of this talk is to provide a sense of what NISQ discoveries to anticipate and a time scale for them.
