Any quantum system inevitably interacts with the environment which causes decoherence. While the environment is generally inaccessible, can we protect our system against noise to maintain its quantum coherence? One technique developed in quantum information science, called the quantum error-correcting codes, does the job. The main idea is to “encode” the system into a subspace of the entireN-qubit space, called the “code space”, such that the errors caused by decoherence of the system can be “corrected”.
