Simulating Electron Transfer on Noisy Quantum Computers
Marvin Gajewski, Alejandro D. Somoza, Gary Schmiedinghoff +3
While simple spin-boson models have been realized on quantum hardware, simulating extended electronic networks with local vibrational environments remains a fundamental challenge i…
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…
The impact of noise on the simulation of NMR spectroscopy on NISQ devices
Andisheh Khedri, Pascal Stadler, Kirsten Bark +5
With the surge of quantum computing platforms that continue to push the boundaries of capabilities of noisy intermediate-scale quantum computers, there is a growing interest in fin…
What is a good use case for quantum computers?
Michael Marthaler, Peter Pinski, Vladimir Rybkin +3
Identify, Transform, Benchmark, Show Quantum Advantage (ITBQ): Evaluating use cases for quantum computers. We introduce a four-step framework for assessing quantum computing applic…
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…
Demonstration of system-bath physics on a gate-based quantum computer
Pascal Stadler, Matteo Lodi, Andisheh Khedri +5
Algorithmic cooling can be used to find correlated states of many-body quantum systems. It is based on quantum circuits that perform nonunitary operations, whose implementation can…
