Tristan Benoist and I have just arXived our paper On bipartite unitary matrices generating subalgebra–preserving quantum operations. We characterize the set of bipartite unitary operators which give quantum operations preserving some subalgebra of the state space, independently of the state of the coupled environment. The main results in the paperContinue reading
RT @AngelaCapelC I'm very happy to announce that Beyond IID 11 will take place in Tübingen from July 31 to August 4! The official website is: sites.google.com/view/beyondi… The call for submissions will open in a few days and the deadline for submissions will be at the beginning of March.
RT @quaintum New paper in @quantumjournal : quantum-journal.org/papers/q-… We map the relationship between the Kochen-Specker (KS) and Gleason's theorems for multiqudit systems. Key insight: multiqubit systems need entangled measurements for both, even though multiqudit systems (w/ d>2) don't 1/4
RT @AngelaCapelC New paper with @yifan_jyf where we provide a generic version of quantum Wielandt's inequality! arxiv.org/abs/2301.08241 Assume you're given two n-dimensional matrices A and B and you want to generate the whole matrix algebra M_n by spanning products on A, B of the form ABBAA...
RT @BartoszRegula The "official" list of Open Quantum Problems is back! Originally started by R. Werner, the list has been maintained by IQOQI Vienna, but the website disappeared a while back. We've been working on updating the problems, and we brought the site back online: oqp.iqoqi.oeaw.ac.at
