Here, there & everywhere Overview of #quantum computing mentions using it to #encrypt transmission of genomic data

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 Uses photon states for intercept-proof key distribution (#QKD)

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")."}}
