In the 3d la nguage the codes emerge as a way to parametrize condensable anyons. Upon c ondensation 3d topological field theory gives rise to 2d CFT at\n the boun dary. This provides a way to construct 2d CFTs from codes - the so-called "code CFTs". This construction has a natural interpretation in terms of a CSS quantum code (defined in terms of the original classical code\, defini ng the CFT). From the holographic point of view a particularly interesting question is that of an ensemble of codes and associated code CFTs. The en semble of boundary theories is holographically dual to "Chern-Simons gravi ty"\, a topological field theory that sums over 3d topologies.\n LOCATION:https://researchseminars.org/talk/HET/58/ END:VEVENT END:VCALENDAR
