Generation of three-qutrit singlet states for three atoms trapped in separated cavities

Abstract Based on quantum Zeno dynamics and adiabatic passage, a scheme for the generation of three-qutrit singlet states for three atoms distributed in three fiber-coupled cavities is proposed, which is insensitive to the fluctuation of atom-cavity coupling rate g and fiber-cavity coupling rate ν when ν ≥ g . Moreover, the influence of atomic spontaneous emission and photon loss on the fidelity is greatly reduced since there are no excitations for atoms, cavities, and fibers.
