Thanks to the development of ever more secure links, quantum cryptography has recently been deployed more widely. ID Quantique has installed quantum links between data centres of KPN, a Dutch telecoms firm; of Battelle, an American non-profit research firm; and of Hyposwiss and Notenstein, two Swiss private banks. It offers links between financial institutions in Geneva and a disaster-recovery centre 50km away. In 2015 researchers at Toshiba in Japan began sending quantum-encrypted genomic data from a research facility in Sendai to Tohoku University, 7km away.

Quantum internet could keep us safe from spying eyes – tech – 18 September 2014 – New Scientist

#Quantum internet could keep us safe from spying eyes http://www.newscientist.com/article/mg22329873.000-quantum-internet-could-keep-us-safe-from-spying-eyes.html#.VQOzLBDF87M Uses photon states for intercept-proof key distribution (#QKD)

QT:{{"
That something is called quantum key distribution (QKD). The technique
transmits photons in particular quantum states to generate a secure
cryptographic key, with which you can encrypt data sent over an
ordinary, non-quantum connection. QKD is far more secure than standard
cryptography, which relies on hard mathematical problems that can
theoretically be cracked, given enough computing power. Any attempt to
intercept a quantum key, however, will disturb the photon’s quantum
states, alerting users not to use the key (see "Unbeatable security")."}}
