Hyper-Invariant MERA: Approximate Holographic Error Correction Codes with Power-Law Correlations
ChunJun Cao, Jason Pollack, Yixu Wang
We consider a class of holographic tensor networks that are efficiently contractible variational ansatze, manifestly (approximate) quantum error correction codes, and can support p…

Approximate recovery and relative entropy I. general von Neumann subalgebras
Thomas Faulkner, Stefan Hollands, Brian Swingle +1
We prove the existence of a universal recovery channel that approximately recovers states on a v. Neumann subalgebra when the change in relative entropy, with respect to a fixed re…

Recovery Map for Fermionic Gaussian Channels
Brian Swingle, Yixu Wang
A recovery map effectively cancels the action of a quantum operation to a partial or full extent. We study the Petz recovery map in the case where the quantum channel and input sta…
