Аннотация:
The transfer of quantum states along spin chains with the XY Heisenberg exchange interaction between nearest-neighbour spins and without decoherence was studied. It was shown that there exists a wide class of engineered mirror-symmetric N-spin-chains that allow the perfect quantum state transfer from one end of each chain to the other. The sets of values of physical parameters of these N-spin-chains were established.
