Once in a while there comes a concept that is just pretty awesome and the Toshiba Quantum Access Networking is one of those concepts!
The Toshiba quantum access networking concept aims to bring crackproof secure networking to up to 64 individuals through assigning each individual a quantum transmitter. The encrypted data is then routed through a central, high-speed photon detector that returns decryption keys. The point of this technology is to reduce the cost of encrypting each user on the network and while the technology won’t be functional over internet scale distances due to signal integrity issues but there is a potential that it someday could be.
