(Phys.org)—One of the most ambitious endeavors in quantum physics just now is to build a large-scale quantum network that could one day span the entire globe. In a modern study,physicists have shown that describing quantum networks in a modern way—as mathematical graphs—can help increase the distance that quantum information can be transmitted. Compared to classical networks, quantum networks have potential advantages such as better security and being faster under certain circumstances.
