Description

This Letter concerns the problem of non-ideal state transfer along the alternating open chain of spins s=1/2 with the XY Hamiltonian. It is found that the state transfer along the chain with even number of spins N (N=4,6,8) may be realized with high probability. Privilege of even N in comparison with odd N is demonstrated
