Quantum error correction and new phases of matter (B01/B02 [Erg.]#)

• Subject Area: Theoretical Condensed Matter Physics
• Term: from 2018 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277101999

Starting with the seminal work of Kitaev, it was realised that various aspects of quantum error correction provided deep insights into problems in condensed matter theory; in particular for our understanding of topological phases. The goal of this supplementary project is to explore some of the new connections between quantum error correction and many-body theory, including thermally stable topological phases and boundary theories.The new theory of local approximate error correcting codes will help extend this correspondence to critical systems, including models of holography.
