dc.descriptionWe studied the quantum state transfer in randomly coupled spin chains. By using local memories storing the information and dividing the task into transfer portion and decoding portion, conclusive transfer was ingeniously achieved with just one single spin chain. In our scheme, the probability of successful transfer can be made arbitrary close to unity. Especially, our scheme is a good protocol to decode information from memories without adding another spin chain. Compared with Time-reversed protocol, the average decoding time is much less in our scheme.
