Congratulations to Dr.  Timo Eckstein for very successfully defending his cumulative doctoral thesis, “Using Symmetries for Near-Term Quantum Computing” His works focus on algorithm development for current and near-term quantum computing platforms. Symmetries, which are mathematically described b...

Last Saturday, the Lange Nacht der Wissenschaften (Long Night of Science) took place across Erlangen, Fürth, and Nürnberg.As part of the Quantum anker event, Ludwig and Verena gave talks as part of the anker event that brought quantum computing to life. Ludwig presented the game Quantenschafkopf, w...

Stefan Wolf, Martin Eckstein and Michael J. Hartmann have published a new pre-print on the arXiv: "Variational Time Evolution Compression for Solving Impurity Models on Quantum Hardware". In this paper we introduce an improved version of a variational time evolution compression algorithm designed t...

Our new work, “Scalable Fluxonium-Transmon Architecture for Error-Corrected Quantum Processors”, has recently been released on the arXiv. In collaboration with colleagues from the Walther-Meissner-Institute in Garching, we introduce a novel hybrid qubit system that combines fluxoniums and transmons...

A new pre-print by Stephan Tasler, Josias Old, Lukas Heunisch, Verena Feulner, Timo Eckstein, Markus Müller, and Michael J. Hartmann has been published on the arXiv. It addresses quantum error correction (QEC), which is a crucial element for fault tolerant quantum computation. Prominent QEC codes...

By: Timo Eckstein, Refik Mansuroglu, Stefan Wolf, Ludwig Nützel, Stephan Tasler, Martin Kliesch, and Michael J. Hartmann. Read the preprint here: https://arxiv.org/abs/2410.21251 Reducing the sampling cost is a major challenge both in the near-term as well as fault-tolerant era of quantum comp...

Beim ersten Weltschafkopftag in Münchberg bei Hof bot sich für unseren Doktoranden Ludwig Nützel die Gelegenheit, mit eingefleischten Schafkopfern einerseits über Schafkopf, aber insbesondere über Quantenmechanik zu reden.

Today, IOP Quantum Science and Technology has published our work which had appeared earlier as a pre-print. This project was jointly realized by Ludwig Nützel, Alexander Gresch, Lukas Hehn, Lucas Marti, Robert Freund, Alex Steiner, Christian D. Marciniak, Timo Eckstein, Nina Stockinger, Stefan Wolf,...

Our recent work, by Bijita Sarma and Michael J. Hartmann, has been published today in Physical Review Applied. In this project, we successfully used reinforcement learning to design quantum controls that achieve very fast two-qubit gates on a transmon tunable coupler circuit. Our work showcases t...

Our work on combinatorial problems has been published in IOP Quantum Science and Technology. It is the result of research performed by Mathias Schmid, alongside Sarah Braun, Rudolf Sollacher, and Michael J. Hartmann. In this project, we explore efficient problem encodings for a specific combinato...
