Abstract:
Simulating quantum systems is one of the most promising areas where quantum computers can offer a decisive advantage over classical computers. This is especially true for open quantum systems, which are notoriously difficult to simulate [1]. One particularly exciting case is the quantum contact process [2], which can be seen as a quantum version of an epidemic and where numerical results point to a novel universality class driven by quantum fluctuations. I report on our latest results on large-scale classical simulations of variants of the quantum contact process and discuss their relevance to current experiments in trapped-ion and Rydberg quantum computers.
