Provable circuit-level thresholds for non-abelian topological phases
Yuanjie Ren, Margarita Davydova, Shankar Balasubramanian +1
We provide an explicit scheme to realize a quantum memory in any 2D non-chiral topological order. For this, we construct syndrome extraction circuits based on the Turaev-Viro path…
A thermally and perturbatively stable classical spin model in two dimensions
Shankar Balasubramanian, Margarita Davydova, Ting-Chun Lin +1
We show that the 2D classical spin model constructed in arXiv:2605.10943 hosts many metastable states at non-zero temperature which are stable to arbitrary Hamiltonian perturbation…
Cups and Gates II: Operads, twists, and addressable intra-code gates
Nikolas P. Breuckmann, Margarita Davydova, Jens Niklas Eberhardt +2
In Part I, we introduced a general framework for constructing logical gates in quantum CSS codes from cohomology invariants, focusing on cup products and their generalizations from…
A passive self-correcting quantum memory in three dimensions
Shankar Balasubramanian, Margarita Davydova, Ting-Chun Lin
We construct a 3D Pauli stabilizer Hamiltonian whose ground state space can encode a qubit for exponential time when coupled to a bath at non-zero temperature. Our construction rec…
