We generalize the concept of folding from surface codes to CSS codes by considering certain dualities within them. In particular, this gives a general method to implement logical operations in suitable LDPC quantum codes using transversal gates and qubit permutations only. To demonstrate our approach, we specifically consider a [[30, 8, 3]] hyperbolic quantum code called Bring's code. Further, we show that by restricting the logical subspace of Bring's code to four qubits, we can obtain the full Clifford group on that subspace.

  1. Targeted Clifford logical gates for hypergraph product codes

    quant-ph 2024-11 conditional novelty 7.0 of 10

    Targeted logical Clifford gates for any hypergraph product code can be built from simple physical gates with support and depth Θ(√n), without ancillas.
