Romanesco codes: Bias-tailored qLDPC codes from fractal codes
Catherine Leroux, Joseph K. Iverson
We introduce and analyze a family of Clifford-deformed bivariate bicycle codes that are tailored for biased noise. Our qLDPC codes are defined on a bipartite hexagonal lattice with…

Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…

Snakes and Ladders: Adapting the surface code to defects
Catherine Leroux, Sophia F. Lin, Przemyslaw Bienias +4
One of the critical challenges solid-state quantum processors face is the presence of fabrication imperfections and two-level systems, which render certain qubits and gates either…
