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…
Optimizing Unitary Coupled Cluster Wave Functions on Quantum Hardware: Error Bound and Resource-Efficient Optimizer
Martin Plazanet, Thomas Ayral
In this work, we study the projective quantum eigensolver (PQE) approach to optimizing unitary coupled cluster wave functions on quantum hardware, as introduced in arXiv:2102.00345…
Compact fermionic quantum state preparation with a natural-orbitalizing variational quantum eigensolving scheme
Pauline Besserve, Michel Ferrero, Thomas Ayral
Assemblies of strongly interacting fermions, whether in a condensed-matter or a quantum chemistry context, range amongst the most promising candidate systems for which quantum comp…
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…
