    Single-Shot Decoding of Good Quantum LDPC Codes

    Quantum Tanner codes constitute a family of quantum low-density parity-check codes with good parameters, i.e., constant encoding rate and relative distance. In this article, we prove that quantum Tanner codes ...

    Shorter unentangled proofs for ground state connectivity

    Can one considerably shorten a proof for a quantum problem by using a protocol with a constant number of unentangled provers? We consider a frustration-free variant of the
