Quantum technologies have the capability of greatly increasing the security of communication systems. Many components are required for a full quantum network including memory, repeaters, routers, and detectors. The efficiencies of quantum communication technologies suffer greatly due to their inherent sensitivity to loss. Low-loss propagation and high detection efficiency can...
Optical quantum communication (QC) has the potential to address the demands of high-speed and maximally-secure communication. In optical QC, information is encoded onto the state of photons. By using entangled photonic states, QC protocols can support fundamentally secure communication for applications which cannot use classical information. To increase the information...
