We design and fabricate a quantum photonic circuit to implement a quantum error correction code. A single logical qubit is encoded with 4 physical qubits to demonstrate its capability of detecting and correcting a single-bit error with an average state fidelity of 86%. We further extend the scheme to demonstrate a fault-tolerant teleportation process.
