Approximate Quantum Codes From Long Wormholes
Gregory Bentsen, Phuc Nguyen, Brian Swingle
We discuss families of approximate quantum error correcting codes which arise as the nearly-degenerate ground states of certain quantum many-body Hamiltonians composed of non-commu…

One-half reflected entropy is not a lower bound for entanglement of purification
Josiah Couch, Phuc Nguyen, Sarah Racz +2
In recent work, Akers et al. proved that the entanglement of purification is bounded below by half of the -Rényi reflected entropy for all ,…
