An antiferromagnetic spin-1 chain as an element of an information storage in quantum computer

Our work generally focuses on the problems of quantum information physics and more specifically on the problem of secret key distribution using the spin1 chain. Spin-1 antiferromagnetic chain allows noiseless information transfer from photonic to spin subsystem and the information storage with 100% fidelity due to features of spin-1 antiferromagnetic chain like as a gap spectrum excitation and a coherent ground state of whole chain with total spin equals to1.
