Many-body post-processing of density functional calculations using the variational quantum eigensolver for Bader charge analysis
Erik Schultheis, Alexander Rehn, Gabriel Breuil
Quantum chemistry and condensed matter physics are among the most promising applications of quantum computers. Further, estimating properties of a material is crucial to evaluate i…
Improved Strategies for Fermionic Quantum Simulation with Global Interactions
Thierry N. Kaldenbach, Erik Schultheis, Niklas Stewen +1
We present efficient quantum circuits for fermionic excitation operators tailored for ion trap quantum computers exhibiting the Mølmer-Sørensen (MS) gate. Such operators commonly a…
Fast gradient-free optimization of excitations in variational quantum eigensolvers
Jonas Jäger, Thierry Nicolas Kaldenbach, Max Haas +1
Finding molecular ground states and energies with variational quantum eigensolvers is central to chemistry applications on quantum computers. Physically motivated ansätze based on…
