Efficient quantum Gibbs sampling of stabilizer codes using hybrid computation

Ivan H. C. Shum, Angela Capel

We present hybrid Gibbs sampling algorithms for the stabilizer code Hamiltonians of the rotated surface code and the toric code with only local quantum algorithms, using $\sim L /2$ …

Efficient encoding of the 2D toric code logical state using local Clifford gates

Ivan H. C. Shum

An algorithm which encodes the $L \times L$ 2D toric code logical state with a circuit of depth $2 L + 1$ , using only local controlled-NOT( $C X$ ) and Hadamard( $H$ ) gates, is presented.
