Quantum communication in spin chains with three-site and Dzyaloshinsky–Moriya interactions
AbstractWe investigate an arbitrary single-qubit state transfer through spin chains with three-site and Dzyaloshinsky–Moriya interactions as well as the quantum discord transfer through double independent spin chains. It is shown that both the three-site and Dzyaloshinsky–Moriya interactions can improve the transfer quality in some cases and the influence of a combination of the three-site and Dzyaloshinsky–Moriya interactions is not simply a linear addition of each contribution. We also find that the three-site coupling may enhance the maximum discord more obviously while the Dzyaloshinsky–Moriya coupling may accelerate the maximum discord more effectively. Furthermore, we show that the quantum discord can always be transferred while the quantum entanglement has a threshold of minimum entanglement to be transferred and may experience entanglement sudden birth and death or even never receive any entanglement for some initial states.
