Reversible computation has been proposed as a future paradigm for energy efficient computation, but so far few implementations have been realized in practice. Quantum circuits, running on quantum computers, are one construct known to be reversible. In this work, we…
We present the experimental implementation of a two-qubit phase gate, using a radio frequency (RF) controlled trapped-ion quantum processor. The RF-driven gate is generated by a pulsed dynamical decoupling sequence applied to the ions’ carrier transitions only. It allows for…
The Frankfurter Allgemeine Sonntagszeitung reported in the article “Quantentechnologien in NRW” about the current research projects throughout NRW. At the University of Siegen, in the research group of Prof. Dr. Christof Wunderlich, the first German quantum computer was put into operation in…
In the project “Quantum Computers with Trapped Ions for Applications” (ATIQ), quantum computer demonstrators are being developed together with users. The 25 project partners are tackling major technical challenges in order to realize German quantum computer demonstrators and make them…
Shape correspondence is a fundamental computer vision task in which vertices of 2D or 3D bodies are mapped to another. This represents a combinatorial optimization problem that takes a lot of time on classical computers. In the publication Q-Match: New approach…
The joint research project MIQRO between the University of Siegen, Leibniz Universität Hannover , Heinrich-Heine-Universität Düsseldorf, QUARTIQ GmbH and eleQtron GmbH as an associated partner is funded by the BMBF and is scheduled to run for 4 years. The quantum computer developed and operated in this project will be…
We congratulate Christian Piltz who was honoured for his PhD work by receiving the nationwide Quantum Future Award of the Federal Ministry of Education and Research!
