Spectral Gap of the Hexagonal AKLT Model via Boundary-State Factorization
Michael J. Kastoryano
We establish a sufficient condition under which overlapping PEPS boundary states satisfy the approximate factorization criterion for a spectral gap. The condition is formulated in…

Subsystem self-correction of the GKP qubit
Brian Chung Hang Cheung, Lasse Bjørn Kristensen, Frederik Nathan +1
Passive quantum error correction, also known as self-correction, is a holy grail in quantum information science. Recent theoretical advances suggest that the Gottesman-Kitaev-Presk…
