For all participants, complimentary on-site and full-board accommodation is provided by the Wilhelm and Else Heraeus Foundation, and there is no conference fee. Please note that the total number of participants is limited to 75. Please note, for postdoctoral researchers, PhD students, and graduate students it is mandatory to present a poster and, thus, to submit an abstract. The scientific organizers will select among the submitted abstracts some presentations for short contributed talks (20 min).

Concept of the Seminar

Macroscopic solid-state quantum effects like the Josephson and quantum Hall effect have been routinely applied in electrical metrology institutes worldwide for more than two decades and are now introduced in companies for industrial calibrations. Additionally, metrological electrical quantum circuits have heavily contributed to the upcoming redefinition of the SI systems of units based on elementary constants which will enter into force on May 20th, 2019. Josephson junction-based SQUID circuits are applied as high-resolution field sensors for e.g. medical applications and scaling towards nano-SQUID systems is advancing. Single electron circuits are used for the generation of quantized electrical currents for electrical metrology and as highly sensitive electrometers allowing to detect the presence and absence of individual charge quanta. In parallel the development of quantum detection schemes based on superconducting cavities and below shot noise superconducting parametric amplifiers may open a way to further enhance the sensitivity of the above detectors. Other fields of solid-state quantum devices have delivered quantum bits, single electron sources with non-classical noise properties, as well as diamond NV center magnetometers with nano scale resolution. More recently, the development of novel topological materials has opened bright new opportunities both for electrical quantum metrology and for topologically protected quantum computation. This seminar aims at bringing together scientists from these different fields of solid-state quantum systems, quantum circuits, and quantum metrology, namely: (i) Single Electron Circuits; (ii) Josephson Circuits; (iii) Spin-Based Quantum Systems; and (iv) Topologically Protected Materials and Devices. The workshop will prepare the ground to discuss the opportunities and challenges of the individual subfields as well as potential synergy between them to foster the development of truly hybrid quantum circuits for future applications in quantum information technology, quantum sensing, quantum metrology and beyond.
