Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, meaning that deviations from error-free operation still occur – albeit (in the best possible scenario) only very rarely. Thus, insights into both the physical origin the and metrological aspects of this fundamental uncertainty are crucial for the further development of quantum circuitry. To this end, scientists from the Physikalisch-Technische Bundesanstalt (PTB) and the University of Latvia have collaborated to develop a statistical testing methodology. Their results have been published in the journal Nature Communications.

TerraQ

In dem neuen Sonderforschungsbereich „TerraQ – Relativistische und quanten-basierte Geodäsie“, der von der DFG zunächst bis 2024 mit rund 9,6 Mio Euro gefördert wird, werden rund 60 Wissenschaftler/ innen aus der Geodäsie und der Physik grundlegend neue Messtechniken, Sensoren und Analysemethoden für Messungen im Weltraum und auf der Erde entwickeln. Zu dem Forschungskonsortium unter Leitung der Leibniz Universität Hannover haben sich sieben Forschungseinrichtungen zusammengeschlossen, darunter die PTB.

An overview of the diverse research landscape of PTB as well as some particularly highlighted topics (for example, PTB research surrounding the International System of Units SI) you will find in the chapter Opens internal link in current windowResearch & Development). In addition, it is always worthwhile to look at the Opens internal link in current windowmain Homepage as well as the homepages of the respective Opens internal link in current windowDivisions. How reputable PTB is among researchers you can see at Opens internal link in current windowPTB in the World of Research. Furthermore, PTB has been – specifically its R&D component, in particular – evaluated repeatedly with excellent results. You can download the respective documents (which are in German only) in the right column as a pdf file.

Scientific publications

In the database Opens internal link in current windowPTB-Publica you can search for scientific publications by PTB staff members. Furthermore, some divisions maintain their own overview lists on the publications of their staff members. These you will find via the respective Opens internal link in current windowhomepages of the divisions.

Research collaborations

The many collaborations of the individual PTB divisions you will find in the Annual Report under the column Opens internal link in current windowFrom the Divisions. International collaborations of PTB, e.g. with other metrology institutes within the framework of the European Metrology Research Programme EMRP/EMPIR, you will find at Opens internal link in current windowInternational Affairs. Some current EMRP dates you will find in the current issue of Opens internal link in current windowPTB-News.
