+++ONLINE KOLLOQUIUM+++ Phase transitions in the complexity of simulating random shallow quantum circuits (MCQST-Kolloquium) (Prof. Aram Harrow)

The appeal of quantum computing is based on the fact that simulating N quantum systems on a classical computer takes time exponential in N. This exponential hardness is known to hold even for shallow quantum circuits, meaning unitary dynamics that run for a constant amount of time. We show that when the quantum circuits are made of random gates on a 2D geometry, they are not always exponentially hard to simulate. [more]
