Efficiently estimating energy expectation values of quantum lattice systems on quantum computers is a crucial subroutine for various quantum algorithms, which can lead to significa…
Solving an Industrially Relevant Quantum Chemistry Problem on Quantum Hardware
Ludwig Nützel, Alexander Gresch, Lukas Hehn +10
Quantum chemical calculations are among the most promising applications for quantum computing. Implementations of dedicated quantum algorithms on available quantum hardware were so…
Large-scale simulations of Floquet physics on near-term quantum computers
Timo Eckstein, Refik Mansuroglu, Piotr Czarnik +5
Periodically driven quantum systems exhibit a diverse set of phenomena but are more challenging to simulate than their equilibrium counterparts. Here, we introduce the Quantum High…
Electronic coherence and coherent dephasing in the optical control of electrons in graphene
Christian Heide, Timo Eckstein, Tobias Boolakee +4
Electronic coherence is of utmost importance for the access and control of quantum-mechanical solid-state properties. Using a purely electronic observable, the photocurrent, we mea…
Variational Hamiltonian simulation for translational invariant systems via classical pre-processing
Refik Mansuroglu, Timo Eckstein, Ludwig Nützel +2
The simulation of time evolution of large quantum systems is a classically challenging and in general intractable task, making it a promising application for quantum computation. A…
Inelastic ponderomotive scattering of electrons at a high-intensity optical travelling wave in vacuum
Martin Kozák, Timo Eckstein, Norbert Schönenberger +1
In the early days of quantum mechanics Kapitza and Dirac predicted that matter waves would scatter off the optical intensity grating formed by two counter-propagating light waves […
Ultrafast scanning electron microscope applied for studying the interaction between free electrons and optical near-fields of periodic nanostructures
M. Kozák, J. McNeur, N. Schönenberger +6
In this paper we describe an ultrafast scanning electron microscope setup developed for the research of inelastic scattering of electrons at optical near-fields of periodic dielect…
