Vienna (particle physics)
I am still working with my former PhD supervisor Beatrix Hiesmayr on quantum information in high energy physics. We are mostly considering neutral Kaon systems and are in close contact to experimentalists at various accelerator facilities. Together with Christoph Spengler from Beatrix' group I have been working on unitary groups and mutually unbiased bases.
Exploiting nonlinear and even non-convex generalizations of the entanglement witness concepts I am contributing a little theory to some of the amazing experiments performed by the group of Anton Zeilinger at the IQOQI Vienna.
