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…
Can a Quantum Computer Simulate Nuclear Magnetic Resonance Spectra Better than a Classical One?
Keith R. Fratus, Nicklas Enenkel, Sebastian Zanker +3
The simulation of the spectra measured in nuclear magnetic resonance (NMR) spectroscopy experiments is a computationally non-trivial problem which, due to its natural interpretatio…
Describing Trotterized Time Evolutions on Noisy Quantum Computers via Static Effective Lindbladians
Keith R. Fratus, Kirsten Bark, Nicolas Vogt +4
We consider the extent to which a Trotterized time evolution implemented on a quantum computer is altered by the presence of decoherence. Given a specific set of assumptions regard…
Quantum algorithms for simulating systems coupled to bosonic modes using a hybrid resonator-qubit quantum computer
Juha Leppäkangas, Pascal Stadler, Dmitry Golubev +14
Modeling composite systems of spins or electrons coupled to bosonic modes is of significant interest for many fields of applied quantum physics and chemistry. A quantum simulation…
