Abstract

Abstract We investigate dynamical decoupling operated by $$2\pi$$ 2 π -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.
