Short bio
Joerg Wrachtrup, Professor and director of the 3rd Institute of Physics and the Centre for Applied Quantum Science, University of Stuttgart (2000, continuing) as well as Max Planck fellow at the MPI for Solid State Research Stuttgart, has pioneered the field of single spin physics by initially doing the very first single electron and subsequently the first single nuclear spins experiments. By combining optics and spin resonance he discovered defects in insulators, most notably defects in diamond, as a valuable system for quantum information processing in novel type of quantum sensor for electric and magnetic fields. He and his group pioneered application of these novel sensor techniques. His current research interest is geared towards application of quantum enhanced sensing in bio, medical as well as material sciences.
Professor Wrachtrup published close to 450 papers in refereed journals with numerous Nature and Science papers, plus reviews in both over the past years. In 2011 and 2017, he was awarded two Advanced Research Grant of the European Research Council, in 2012 he received the Leibniz Price of the German Science Foundation, in 2013 the Bruker Prize and in 2014 the Max Planck Research Award and in 2020 the European Physics Prize. He is member of the Berlin Brandenburg Academy of Science and has continuously been listed as 鈥淗ighly Cited Researcher鈥� since 2014.
Title
Quantum Sensing on the Nanoscale
Abstract
Spin defects in wide-bandgap semiconductors enable quantum sensing with spatial resolutions down to a few nanometers, opening a wide range of applications in both material- and biosciences. The sensor spin is inherently sensitive to multiple external parameters, like temperature, magnetic and electric field or force. However, through tailored Hamiltonian engineering, the system can be made selectively responsive to specific quantities鈥攕uch as temperature鈥攚hile remaining insensitive to others, such as magnetic fields. This talk will present demonstrations of quantum sensing across various fields from biophysics to battery research and discuss how tricks from quantum computing can enhance sensor performance and signal processing capabilities.
