Quantum networks, systems that connect devices using quantum mechanical effects, could potentially allow users to share information more securely and efficiently. Building these networks typically entails linking stationary qubits, units of quantum information encoded in trapped ions or other physical systems, using photons (particles of light) transmitted through optical fibers.
