Symmetric-cycle pulse sequence for dynamical decoupling of local fields and dipole–dipole interactions

Аннотация

We have proposed a new pulse sequence for the dynamical decoupling of decoherence effects in the ensemble of nuclear spins. The sequence provides a symmetric cycle that offers a strong suppression of the decoherence effects caused by the dipole–dipole interactions and the inhomogeneous local magnetic fields in nuclear spin ensemble dynamics. We have discussed a potential of the proposed pulse sequence for the long-lived storage of the multi-qubit quantum states.
