[quantum-info] Quantum information seminar today

[Markus Mueller]

Hi all,

please join us today 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.

Best,
Markus
