In a recent Physical Review Letters, a team of researchers from the Walther-Meißner-Institute (WMI) of the Bavarian Academy of Sciences and Humanities (BAdW), the Technical University of Munich (TUM), the ETH Zürich, the University of Konstanz and the Universidad Autónoma de Madrid (UAM) has demonstrated the transfer of spin information between two separated ferromagnetic metal strips harnessing magnetic excitations, providing a new avenue for spintronics.
The new permanent exhibition on "Light & Matter" has been jointly developed by the Cluster of Excellence MCQST and the Deutsches Museum. "The new exhibition makes quantum technology and quantum optical phenomena tangible for the broad public", Rudolf Gross, spokesperson of MCQST and member of the Fachbeirat of the exhibition says. "It is even better that the exhibition also allows us to present key MCQST results and an outlook on their future applications", he adds.
WMI scientists provide important new insight into transmon ionization (TI). This process is detrimental to superconducting qubit coherence and limits the performance of microwave single-photon detectors (SPDs) based on a 3D multimode cavity coupled to a transmon qubit. Based on their detailed study, the WMI researchers can propose potential solutions for further increasing the quantum efficiency of SPDs, which are key elements for for advancing quantum communication and sensing technologies.
On Saturday, May 4th, the Bavarian Academy of Science opened its doors to the public. At the Residenz in Munich, over 5.500 visitors explored the various institutes that constitute the BAdW. On the forefront, the WMI showed interested adults and kids the fascinating physics that take place at ultra-low temperatures, ranging from experiments with liquid nitrogen and superconducting materials all the way up to modern quantum computing.
WMI hosts the kick-off seminar of the jDPG-Kolleg "Next Generation Computing". About 30 PhD students delved into questions spanning from the technical implementation of quantum computers, the availability and use cases of quantum algorithms, potential applications, to broader social implications. The efforts of the students are complemented by an advisory board from the scientific community (Hans Huebl - WMI, Jeanette Lorenz - FhG), industry (Adrian Auter - IQM) and organisations briding the gap between industry and academia (Andreas Böhm - Bayern Innovativ). The opening talk by Max Werninghaus highlighted sc quantum processors and perfectly set the stage for the discussions during the weekend.
