Smoothing out the quantum noise
David Reilly from Sydney University will be at UQ this friday to give the physics colloquium. Unfortunately, I will be in Sydney but plan on catching up with David on thursday. I knew David when he was a Ph.D student at UNSW. He recently returned to Sydney after a postdoc in Charlie Marcus' group at Harvard. He published a really nice Science paper and Physical Review Letter, characterising how electron spins in double quantum dots are decohered by the fluctuating nuclear spins. A few years back Sam Young Cho and I considered how such double quantum dots could be used for a solid state realisation of Werner states (i.e., quantum states which are entangled but do not violate Bell inequalities). An associated talk which I will give at Sydney University on thursday is here.
