By Jacob Aron Secure quantum networks could soon be stretching across Europe, thanks to a new scheme that ups the theoretical limit for transmitting messages using the weird properties of quantum mechanics. Quantum key distribution (QKD) is a way of exchanging secret encryption keys using photons – particles of light – encoded with certain quantum properties. Done properly, it is impossible to hack,
