Extended Data Fig. 2: Fidelities for partially FT code switching.

Logical process fidelities of switching from the [[10, 1, 2]] to the [[7, 1, 3]] code, using a non-FT (blue), a partially FT (orange) and FT (green) scheme. Partially FT switching does not require additional measurements or auxiliary qubits and only includes the agreement check of opposing pairs of operators. For FT switching, we add flag qubits for fully FT stabilizer measurements. The error bars show standard deviations, determined as discussed in ‘Quantum state and process tomography’.
