We have, with Moto Fukuda, a new paper on the arXiv, Enumerating meandric systems with large number of components, which deals with the enumeration of meandric systems. In combinatorics, a meander on $2n$ points is a closed, self-avoiding plane curve, which intersects a given line $2n$ times. Below, the meandersContinue 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
