(HelpNetSecurity) Researchers at the University of Rochester and Cornell University have taken an important step toward developing a communications network that exchanges information across long distances by using photons, mass-less measures of light that are key elements of quantum computing and quantum communications systems.
The research team has designed a nanoscale node made out of magnetic and semiconducting materials that could interact with other nodes, using laser light to emit and accept photons.
The development of such a quantum network -designed to take advantage of the physical properties of light and matter characterized by quantum mechanics – promises faster, more efficient ways to communicate, compute, and detect objects and materials as compared to networks currently used for computing and communications.
