Quantum systems are subject to random phase errors that can dramatically affect the fidelity of a desired quantum operation or measurement, but existing quantum error correction techniques have large resource requirements, motivating a search for alternative strategies. The authors experimentally validate the use of the dynamical decoupling technique to suppress qubit error rates, using novel optimized pulse sequences that suppress errors by orders of magnitude compared to other existing sequences.
