Ladder Floquet code[1]
Description
Floquet code defined on a ladder qubit geometry, with one qubit per vertex. The check operators consist of \(ZZ\) checks on each rung and alternating \(XX\) and \(YY\) check on the legs.
Decoding
Period-four measurement sequence utilizing two-qubit measurements [1].
Parent
- Hastings-Haah Floquet code — The ladder Floquet code is the first 1D Floquet code.
Cousin
- \([[4,2,2]]\) Four-qubit code — The smallest example of the ladder Floquet code is a dynamical version of the \([[4,2,2]]\) code [2].
