Quantum Technology

Just as PTB was once – thanks to its measuring skills – at the beginning of quantum mechanics, PTB is now driving the second quantum revolution’s wave of metrological possibilities – with the next generations of atomic clocks, even more precise electrical standards and innovative measurement capabilities in medicine.

PTB – the National Metrology Institute of Germany

PTB's profile of tasks

In Braunschweig and Berlin, time comes from atomic clocks, lengths are measured far into the nano-world, scientists do research on fundamental questions concerning the physical units, and the employees in the laboratories calibrate measuring instruments, meeting the most demanding requirements. Therefore, the Physikalisch-Technische Bundesanstalt is among the top names in metrology worldwide. As Germany's national metrology institute, PTB is Germany's highest authority when it comes to correct and reliable measurements. It is the supreme technical authority of the Federal Ministry for Economic Affairs and Climate Action (BMWK) and employs a total of approx. 1900 staff members. PTB operates an integrated Opens internal link in current windowquality management system which covers the four interlinked field of business.
