In our recent work, by Timo Eckstein, Refik Mansuroglu, Stefan Wolf, Ludwig Nützel, Stephan Tasler, Martin Kliesch, and Michael J. Hartmann, that has just been published as a preprint: https://arxiv.org/abs/2410.21251, we present an energy estimation technique that is tailored to quantum lattices sy...

"Variational Hamiltonian simulation for translational invariant systems via classical pre-processing, a work published in 2023 in Quantum Science and Technology by our former PhD student Refik Mansuroglu (now at Universität Wien), with contributions from Timo Eckstein, Ludwig Nützel, and Sam Wilkins...

In our recent work, by Timo Eckstein, Refik Mansuroglu, Piotr Czarnik, Jian-Xin Zhu, Hartmann Michael, Lukasz Cincio, Andrew Sornborger and Zoë Holmes, that was published just today in Nature Partner Journal Quantum Information,  we present an algorithm to simulate periodically time-dependent Hamilt...

During the 2023-2024 winter semester's course on quantum computing given by Prof. Hartmann, students were able to participate in an optional series of tutorials on the Qiskit package, which allows them to build quantum circuits, and then either simulate them on their computers, or run them on IBM's ...

Simulation of quantum chemical problems is one of the most promising avenues to practical quantum advantage. However, it remains a challenge on contemporary quantum computers without error correction to reach the required 'chemical accuracy'. Prior works have therefore focussed on very simple molecu...
