The orthogonality speed of two-qubit state interacts locally with spin chain in the presence of Dzyaloshinsky-Moriya interaction

D. A. M. Abo-Kahla, M. Y. Abd-Rabbou, N. Metwally

The orthogonality time is examined for different initial states settings interacting locally with different types of spin interaction: $XX$, Ising and anisotropic models. It is sho…
