Turning qubit noise into an advantage: Automatic state preparation and long-time dynamics for impurity models on quantum computers
Corentin Bertrand, Pauline Besserve, Michel Ferrero +1
Noise is often regarded as a limitation of quantum computers. In this work, we show that in the dynamical mean field theory (DMFT) approach to strongly-correlated systems, it can a…

Enabling large-depth simulation of noisy quantum circuits with positive tensor networks
Ambroise Müller, Thomas Ayral, Corentin Bertrand
Matrix product density operators (MPDOs) are tensor network representations of locally purified density matrices where each physical degree of freedom is associated to an environme…
