Variational Quantum Subspace Construction via Symmetry-Preserving Cost Functions
Hamzat A. Akande, Alexandre Perrin, Bruno Senjean +1
Determining low-energy eigenstates in electronic many-body quantum systems is a key challenge in computational chemistry and condensed-matter physics. Hybrid quantum-classical appr…
Variational minimization scheme for the one-particle reduced density matrix functional theory in the ensemble N-representability domain
Matthieu Vladaj, Quentin Marécat, Bruno Senjean +1
The one-particle reduced density-matrix (1-RDM) functional theory is a promising alternative to density-functional theory (DFT) that uses the 1-RDM rather than the electronic densi…
State-Averaged Orbital-Optimized VQE: A quantum algorithm for the democratic description of ground and excited electronic states
Martin Beseda, Silvie Illésová, Saad Yalouz +1
The electronic structure problem is one of the main problems in modern theoretical chemistry. While there are many already-established methods both for the problem itself and its a…
Neutral electronic excitations and derivative discontinuities: An extended -centered ensemble density functional theory perspective
Filip Cernatic, Pierre-François Loos, Bruno Senjean +1
This work merges two different types of many-electron ensembles, namely the Theophilou-Gross-Oliveira-Kohn ensembles of ground and neutrally-excited states, and the more recent …
