In all above mentioned experiments, spin chains on CuN 2 were created in control way by atomic manipulation with scanning tunnelling microscopy (STM). Spin chains with defined entanglement can be produced by changing the composition and coupling within the chains. the possibility to tune entanglement in chains of magnetic adatoms on a CuN 2/Cu(001) surface was demonstrated.
In very recent remarkable experiments of Choi et al 13. Recent experiments on engineered small magnetic units on CuN 2 have demonstrated the possibility to study and control their spin states which is a very significant step towards atomic-scale memories 19, 20, 21, 22, 15, Moreover, it has been 19 shown that data can be stored in antiferromagnetic atomic-scale structures on CuN 2 allowing to achieve data storage densities that are about 100 times higher than those in modern hard drives 22. Gauyacq and Lorrente 18 have shown that decay from one state to another in such system strongly depends on the degree of entanglement of the local spins in the chain. have observed very long lifetimes in the case of antiferromagnetic Fe 3 chains on CuN 2. For example, thin insulating layers, specifically CuN 2 on Cu(001) surface, provide significant decoupling between spins in surface-supported nanostructures and the bulk electrons in the metal below, resulting in relatively long-lived spin states 17, 14, Yan et al 17. Several experiments have shown that entanglement in atomic-scale nanostructures on surfaces can survive at low temperatures even in the presence of decoherence caused by the environment 13, 14, 15, To reduce the decoherence insulating substrates can be used 16. Antiferromagnetic spin chains can exhibit entanglement over long distances 10, 11, The entanglement in antiferromagnetic chains can be increased by increasing the temperature or the external field 12. Spin chains are promising candidates for the generation of entanglement and qubit teleportation 2, 3, 4, 5, 6, 7, 8, The transfer of a classical information along a quantum spin chain has been found to strongly depend on the quantum magnetic phases in the chain which can be tuned by the transverse magnetic field 9. Quantum entanglement between spins is considered as a key resource for such future applications 1. The emerging field of quantum engineering has the potential to create new quantum technologies.
