Quantum networks descend from the study of Quantum cryptography. The idea of a quantum network emerged after successful experiments on quantum teleportation. When two companies (one from Switzerland, 'idQuantique', and another from the USA, 'MagiQTech') released practical communication devices based upon the rules of quantum mechanics, the need for a secure network capable of utilizing quantum principles was realized. These networks are now known as quantum communication networks. In these networks, data are communicated as quantum states through the technique of entanglement via an optical fiber link.
Quantum technology is the future, no doubt. The impact of computing devices based on quantum effects finally entering service would be vast and of immense positive consequence to the scientific world, and hence mankind, comparable with the invent of the microchip. While this future might still seem far fetched, judging from the number of successful [...]
