Quantum Simulation of Magnetic Materials: from Ab-Initio to NISQ
Pascal Stadler, Florian G. Eich, Benedikt M. Schoenauer +5
Quantum computers are increasingly accessible, yet demonstrations of physically meaningful simulations for real materials remain scarce. In our work we simulate low-energy magnetic…

System-bath model for quantum chemistry
Dmitry S. Golubev, Reza G. Shirazi, Vladimir V. Rybkin +3
We propose an approximate mapping of a molecular Hamiltonian to a Hamiltonian of qubits, which allows for high accuracy quantum chemistry calculations of vertical excitation energi…

A method to derive material-specific spin-bath model descriptions of materials displaying prevalent spin physics
Benedikt M. Schoenauer, Nicklas Enenkel, Florian G. Eich +4
Magnetism and spin physics are true quantum mechanical effects and their description usually requires multi reference methods and is often hidden in the standard description of mol…
