Emulation of large-scale qubit registers with a phase-space approach
Christian de Correc, Denis Lacroix, Corentin Bertrand
A phase-space approach is used and benchmarked for the simulation of the continuous-time evolution of large registers of qubits. It is based on a statistical ensemble of independen…
Many-body Quantum Score: a scalable benchmark for digital and analog quantum processors and first test on a commercial neutral atom device
Harold Erbin, Pierre-Louis Burdeau, Corentin Bertrand +2
We propose the Many-body Quantum Score (MBQS), a practical and scalable application-level benchmark protocol designed to evaluate the capabilities of quantum processing units (QPUs…
Approximate combinatorial optimization with Rydberg atoms: the barrier of interpretability
Christian de Correc, Thomas Ayral, Corentin Bertrand
Analog quantum computing with Rydberg atoms is seen as an avenue to solve hard graph optimization problems, because they naturally encode the Maximum Independent Set (MIS) problem…
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…
