Time Crystals on Quantum Devices
Gonzalo Camacho, Benedikt Fauseweh
Time crystals are nonequilibrium phases of matter characterized by the emergence of temporal ordering, in which an interacting many-body system develops robust structure in its tim…
Emergent-Coupling-Based Ansatz Evaluated on a Superconducting Quantum Processor
Alina Joch, Kevin Lively, Benedikt Fauseweh
The performance of the variational quantum eigensolver depends critically on the choice of ansatz. In this work, we experimentally evaluate the emergent-coupling-based ansatz (ECBA…
Non-local edge mode hybridization in the long-range interacting Kitaev chain
David Haink, Andreas A. Buchheit, Benedikt Fauseweh
In one-dimensional p-wave superconductors with short-range interactions, topologically protected Majorana modes emerge, whose mass decays exponentially with system size, as first s…
Quantum Software Ecosystem Design
Achim Basermann, Michael Epping, Benedikt Fauseweh +7
The rapid advancements in quantum computing necessitate a scientific and rigorous approach to the construction of a corresponding software ecosystem, a topic underexplored and prim…
