Entanglement of purification and projection operator in conformal field theories
We investigate entanglement of purification (EoP) in conformal field theory. By using Reeh-Schlieder theorem, we construct a set of the purification states for ρAB, where ρAB is reduced density matrix for subregion AB of a global state ρ. The set can be approximated by acting all the unitary observa...
