Wayne Witzel

Quantum Computer Science. Biography My primary research is in quantum information.  I have pioneered cluster expansion methods for calculating the decoherence rate of a spin qubit in the presence of impurity nuclear and electron spins.  I've also studied dynamical decoupling strategies in this context.  I've broadened my research into more...
