Safe Messaging

Cybersecurity experts have long warned that quantum computers, whenever it is that they become useful, will render useless most conventional forms of encryption. This new satellite experiment, which is described in research published in the journal Nature, suggests that it may be possible to send secure messages yet.

“A remarkable feature of the entanglement-based quantum cryptography as we demonstrated here is that such security is ensured even if the satellite is controlled by an adversary,” University of Science and Technology physicist Jian-Wei Pan told Space.com.
