We investigate dynamical decoupling operated by 2π-pulses in a two-level subspace of a multilevel system showing that it may lead to selective decoupling. This provides a flexible strategy for decoupling transitions in a quantum network, when control to directly address them is not available, which can be used to control internode interaction or actively suppress decoherence.

Abstract
We investigate dynamical decoupling operated by 2π-pulses in a two-level subspace of a multilevel system showing that it may lead to selective decoupling. This provides a flexible strategy for decoupling transitions in a quantum network, when control to directly address them is not available, which can be used to control internode interaction or actively suppress decoherence.File in questo prodotto:
