|Title:||Preserving quantum coherence using optimized open-loop control techniques|
|Published:||May 16, 2010|
|Abstract:||We describe experimental and theoretical studies of open-loop quantum control techniques known as dynamical decoupling (DD) for the suppression of decoherence-induced errors in quantum systems. Our experiments on trapped atomic ion qubits demonstrate that it is possible to optimize the construction of DD sequences for a given noise power spectral density. Studies of novel sequences derived analytically or through numerical optimization -- while maintaining fixed control resources -- demonstrate large gains in our ability to preserve quantum coherence in arbitrary noise.|
