Abstract
Dynamical decoupling is an established tool for protecting the quantum state of a qubit from decoherence. This paper extends the simplest dynamical decoupling technique for qubits—the Carr-Purcell-Meiboom-Gill's two-pulse rephasing sequence—to qudits with an arbitrary number of states. The pulse sequences introduced here are particularly well suited for dynamical rephasing of the collective coherence of inhomogeneously broadened ensembles of atomic qudits.
