Hi all,

please join us tomorrow at 4 pm in the Alice Room for a quantum information seminar by Isaac Kim.


Title: Application of conditional independence to gapped quantum many-body systems
Speaker: Isaac Kim (Caltech)

Abstract:
It is widely known in the quantum information community that the states that satisfy strong subadditivity of entropy with equality have the form of quantum Markov chain. Based on a recent strengthening of strong subadditivity of entropy, I will describe how such structure can be exploited in the studies of gapped quantum many-body system. In particular, I will describe a diagrammatic trick to i) give a quantitative statement about the locality of entanglement spectrum ii) perturbatively bound changes of topological entanglement entropy under generic perturbation.
