We experimentally implement the Floquet-Bacon-Shor code on a superconducting quantum processor, encoding a dynamical logical qubit within a 3x3 lattice alongside a conventional static logical qubit, demonstrating fault-tolerant encoding, universal single-qubit logical gates on the dynamical qubit, and an error-detected logical Bell state with fidelity 75.9%.
