SUMMARY:Locality\, universality\, and quantum dynamics with measuremen
 ts\, R. G. Herb Condensed Matter Seminar\, Aaron Friedman\, UC Boulder
DESCRIPTION:I will present a recently developed formalism for quantum 
 measurements that is both technically powerful and conceptually transp
 arent. This framework is the basis for new results based on condensed 
 matter principles like locality and universality that were not previou
 sly thought possible—including extending the Lieb-Robinson Theorem t
 o dynamics with measurements and proving deep connections between meas
 urement-based quantum computation and topological order. In contrast t
 o the conventional wisdom that measurements destroy locality\, we find
   a maximum enhancement to the speed of quantum information in measure
 ment-assisted protocols\, establishing a precise notion of locality. I
 ’ll discuss the formal resolution to the EPR paradox\, constraints o
 n quantum teleportation\, error correction\, routing\, and the prepara
 tion of useful resource states (e.g.\, Bell\, GHZ\,  Dicke\, and squee
 zed states). I’ll present optimal quantum protocols that achieve the
 se tasks\, reveal new resource tradeoffs\, and discuss important impli
 cations for measurement-based quantum computing and its fundamental co
 nnection to symmetry-protected topological order. Finally\, I'll comme
 nt on other applications relevant to condensed matter and future appli
 cations of this work.
