Perfectly Secure Quantum Internet Running At Los Alamos For Two Years

jpwilliams writes: A network leveraging quantum mechanics has been under testing for two years at Los Alamos National Labs.

Because observing a message inevitably changes it, messages based on quantum mechanics are theoretically perfectly secure.

The Los Alamos network works off of a hub and spoke model, where all messages go into a central hub and then out to another end point in the network.

Apparently, some companies are already providing quantum networking, with banks and other security firms interested.
