RushHour-style dynamic reconfiguration could, within two years, let small surface-code devices execute error-corrected circuits with lower qubit overhead by reallocating lattice-surgery patches between operations.
Near-term quantum processors have too few physical qubits for static logical-qubit layouts; if the architecture's scheduling can be implemented on existing control systems, testbed demonstrations could show reduced time or space overhead for fault-tolerant operations.
