Quantum Information Science with spins and photons

Color centers and other spin qubits

We investigate color center formation far from equilibrium, e.g. using high intensity short ion pulses that can locally create very high temperatures for short times in materials such as diamonds.


We work together with Liang Tan et al. for theoretical support of our experiments and Ed Barnard for confocal imaging.
