Here, we evaluate the performance of different fault-tolerant encodings and fault-tolerant parity-check measurement circuits for the distance-3 color code ([[7,1,3]] code) mapped to a 2D square lattice with limited local connectivity. We demonstrate how fault-tolerant designs for the level-1 encoding (7-qubit logical state) can be accomplished using two-qubit gates between nearest-neighbor qubits, mid-measurements, and post-selection. Additionally, we illustrate how fault-tolerant transport can be implemented in a static array using SWAP and CNOT gate teleportation to perform logical gates between encoded qubits and to prepare larger logical states.
