Every quantum processor is affected by noise from the environment and imperfections of the gate operations. The essential method to correct for these errors and therefore enabling fault tolerant quantum computation is known as quantum error correction. Here we report on the experimental realization of a quantum error correcting code, where a logical qubit is encoded within 7 ion qubits, the minimal instance of a topological stabilizer code. We demonstrate the capability of detecting arbitrary single qubit errors by measuring the full syndrome table. Additionally, we show the realization of unitary operations on the logical qubit, which is the basic requirement for fault tolerant quantum computation.
