Example Concept: Quantum error correction for superconducting qubits typically uses the surface code, which arranges qubits in a 2D lattice. Each logical qubit is encoded into a grid of physical qubits, allowing for the detection and correction of both bit-flip and phase-flip errors through stabilizer measurements. By repeatedly measuring these stabilizers, errors can be identified and corrected without directly measuring the logical qubit state, thus preserving quantum information.
