Performance comparison of optimization methods on variational quantum algorithms
Xavier Bonet-Monroig, Hao Wang, Diederick Vermetten +5
Variational quantum algorithms (VQAs) offer a promising path toward using near-term quantum hardware for applications in academic and industrial research. These algorithms aim to f…
Ensemble Density Functional Theory of Neutral and Charged Excitations
Filip Cernatic, Bruno Senjean, Vincent Robert +1
Recent progress in the field of (time-independent) ensemble density-functional theory (DFT) for excited states are reviewed. Both Gross-Oliveira-Kohn (GOK) and -centered ensembl…
Analytical nonadiabatic couplings and gradients within the state-averaged orbital-optimized variational quantum eigensolver
Saad Yalouz, Emiel Koridon, Bruno Senjean +3
In this work, we introduce several technical and analytical extensions to our recent state-averaged orbital-optimized variational quantum eigensolver (SA-OO-VQE) algorithm (see Ref…
Encoding strongly-correlated many-boson wavefunctions on a photonic quantum computer: application to the attractive Bose-Hubbard model
Saad Yalouz, Bruno Senjean, Filippo Miatto +1
Variational quantum algorithms (VQA) are considered as some of the most promising methods to determine the properties of complex strongly correlated quantum many-body systems, espe…
Orbital transformations to reduce the 1-norm of the electronic structure Hamiltonian for quantum computing applications
Emiel Koridon, Saad Yalouz, Bruno Senjean +3
Reducing the complexity of quantum algorithms to treat quantum chemistry problems is essential to demonstrate an eventual quantum advantage of Noisy-Intermediate Scale Quantum (NIS…
