Quantum error correction with bosonic-Bacon-Shor codes

In this talk, we present numerical results for error correction where single-mode bosonic codes are concatenated with a Bacon-Shor code. We compare different bosonic codes, including cat- and binomial codes, to conventional two-level systems at the ground level. Break-even points and logical error rates are computed for small codes and a circuit level noise model that includes photon loss and dephasing.
