能够纠正所有单量子比特错误的最小量子码是基于五个量子比特的。我们实验实现了编码，解码和纠错量子网络，使用核磁共振标记巴豆酸的五个自旋子系统。通过过程的断层扫描验证了纠正每个错误的能力。使用纠错基准量子网络进行了讨论，我们推断，在我们的实验中实现的保真度是足够的保持纠缠。
The smallest quantum code that can correct all one-qubit errors is based on five qubits. We experimentally implemented the encoding, decoding, and error-correction quantum networks using nuclear magnetic resonance on a five spin subsystem of labeled crotonic acid. The ability to correct each error was verified by tomography of the process. The use of error correction for benchmarking quantum networks is discussed, and we infer that the fidelity achieved in our experiment is sufficient for preserving entanglement.
