Partial structural restoring of two-qubit transferred state

Publication date: Available online 19 September 2018Source: Physics Letters AAuthor(s): A.I. ZenchukAbstractWe consider the communication line with two-qubit sender and receiver, the later is embedded into the four-qubit extended receiver. Using the optimizing unitary transformation on the extended receiver we restore the structure of the non-diagonal part of an arbitrary initial sender's state at the remote receiver at certain time instant. Obstacles for restoring the diagonal part are discussed. We represent examples of such structural restoring in a communication line of 42 spin-1/2 particles.
