Different approaches have improved the sensitivity of either electron or nuclear magnetic resonance to the single spin level. For optical detection it has essentially become routine to observe a single electron spin or nuclear spin.
Science and teaching at the institute comprises solid state quantum optics and spintronics with applications in modern microscopy and metrology applications in e.g. biophysics. Common to all experimental approaches is the use of photons as central tool. Besides set-ups in the field of optics and spin control facilities at the institute comprise synthesis, implantation and structuring of carbon materials, protein purification and cell culturing.
