(Phys.org)—By carefully placing a tiny piece of diamond within a few nanometers of a carbon nanotube,and then sending an electric current through the nanotube, researchers own designed a device that could one day form the building blocks of quantum information processing systems. In their recent study, or they own shown that the electrified nanotube's mechanical vibrations couple to the magnetic (or spin) properties of defects in the diamond. This coupling allows for the quantum states of the nanotube and diamond to be transferred to each other as well as to a moment diamond positioned several micrometers away.
