DESCRIPTION:Prof. Jörg Wrachtrup\, University of Stuttgart\nBio: Jörg Wr
 achtrup is professor for experimental physics and director of the 3rd Inst
 itute of Physics at University of Stuttgart and Max Planck fellow at the M
 ax Planck Institute for Solid State Research. His research interests compr
 ise solid state quantum spintronics and quantum optics as well as precisio
 n quantum metrology.\n\nProf. Wrachtrup has pioneered the field of quantum
  spin physics by initially doing the very first single electron first sing
 le nuclear spins experiments in solids. By combining photonics and spin re
 sonance he discovered defects in insulators\, most notably defects in diam
 ond as a valuable system for quantum information processing and novel type
  of quantum sensors. He and his group carried out the first quantum operat
 ions with diamond electron and nuclear spins and designed the first diamon
 d spin based quantum sensor which he is now applying to material science a
 nd bioanalytics.\nThe accuracy of measurements is limited by quantum mecha
 nics. Ingenious demonstrations\, like measuring gravitational fields or ti
 me have explored accuracy limits and reached fundamental obstructions Yet\
 , precision measurements so far are restricted to macroscale and dedicated
  environments.\n\nIn this talk I will discuss spin quantum sensors compris
 ing a single electron spin plus a nuclear spin quantum register. With such
  a system we measure a variety of quantities including electric and magnet
 ic fields\, temperature\, and force. We use nuclear spins to enhance the m
 easurement accuracy of the electron spin e.g. via quantum error correction
  or as ancillary quantum bits as memory or for quantum Fourier transformat
 ion. I will present a variety of applications ranging from quantum simulat
 ions to imaging of cellular structures.
