Entanglement at a Scale and Recovery Maps
---
SKYPE TALK
I discuss the amount of information in quantum
field theory states reduced to a region,
that cannot be recovered from its subregion
density matrices. One can reconstruct the
density matrix from its subregions using
recovery maps. The vacuum of a conformal
field theory is a quantum Markov state and
the fixed point of both transformations.
I define the entanglement of scaling as a
measure of entanglement at a scale, and mention
connections with C-theorems proofs in 2,
3 and 4 dimensions.
