Publication in Physical Review Research: “Quantum convolutional neural network for phase recognition in two dimensions”
On November 7th, Physical Review Research has published our work which had appeared earlier as a pre-print. This project was jointly realized by Leon C. Sander, Nathan A. McMahon, Petr Zapletal, and Michael J. Hartmann. In this work, we construct a QCNN that can perform phase recognition in two dimensions and correctly identify the phase […]

Hats off & hat on: Dr. Timo Eckstein!
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 by groups, divide the full space of possibilities, the Hilbert space, into smaller sectors. If a symmetry is […]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.

Quantum Games at the Long Night of Science
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, which he developed himself and Verena talked about quantum […]

New preprint released: “Variational Time Evolution Compression for Solving Impurity Models on Quantum Hardware”
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 to solve impurity models on quantum computers, an important task in condensed […]

New preprint: “Scalable Fluxonium-Transmon Architecture for Error Corrected Quantum Processors”
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 within a single architecture. We show that this system exhibits excellent scaling properties, opening a new pathway […]Our new work, “Scalable Fluxonium-Transmon Architecture for Error-Corrected Quantum Processors”, has recently been released on the arXiv.

New preprint “Optimizing Superconducting Three-Qubit Gates for Surface-Code Error Correction” and parallel preprint released
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 are stabilizer codes, for which the stabilizer operators are read […]
