The application of superconducting circuits for the realization of future quantum electronics has attracted strong interest, in particular regarding the implementation of quantum information
Within the Walther-Meißner-Seminar national and international experts present talks on current research related to the research topics of the Walther-Meißner-Institute such as quantum information
We describe a novel scheme for the generation of stationary entanglement between two separated qubits that are driven by a purely thermal photon source. While in this scenario the qubits remain in a
Quantum communication in the microwave regime is set to play an important role in distributed quantum computing and hybrid quantum networks. However, typical superconducting quantum circuits require

Wireless power transfer (WPT) systems have emerged as a key technology for the future charging
infrastructure. Besides full system efficiency, the power densities of the transmission coils are key
We systematically study the performance of compact lumped element planar microwave Nb70Ti30N (NbTiN) resonators operating at 5 GHz in external in-plane magnetic fields up to 440 mT, a broad

Technical Description of the WMI Helium Pump
A vertical cross-section, a horizontal cross-section along the line A-B and a vertical cross-section of part of the pump systems is shown in the
The European Union has awarded €25 million to the SUPREME consortium, consisting of 23 European companies and research organisations, including WMI.
Over the past two decades, the helium price has been strongly increasing. The reason is a growing demand and a change in supply chains. Although helium prices were doubling from 2002 to 2012, both
Luis Flacke was member of the Gross groups as a Master and Ph.D. Student between 2017 and 2021.
Master Thesis: Spin Pumping and Spin Wave Damping in Co25Fe75 Thin Film Heterostructures (2018) Ph.D.
We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin-film heterostructures of antiferromagnetic insulating (0001)-oriented alpha-Fe2O3 (hematite) and Pt. We measure their
The ability to control the Gilbert damping which determines the lifetime of spin information is crucial for designing spintronic and magnonic devices. Thus, controlling the Gilbert damping parameter
Understanding the excitations of quantum materials is essential for unraveling how their microscopic constituents interact. Among these, particle-hole excitations form a particularly important class,
