An international team of researchers (USA – University of Chicago, Argonne National Laboratory, Chicago, Japan, Sweden, Hungary) has demonstrated they could electrically control quantum states embedded in silicon carbide. The quantum states in silicon carbide have the added benefit of emitting single particles of light with a wavelength near the telecommunications band which makes them well suited to long-distance transmission through the same fiber-optic network. They found that by using the diode, a one-way switch for electrons the quantum signal suddenly became free of noise and was almost perfectly stable mitigating the impurity issue. The work brings us one step closer to the realization of systems capable of storing and distributing quantum information across the world’s fiber-optic networks…read more. TECHNICAL ARTICLE 1Â , 2
