Amplifying information – the key to the quantum Internet?
The establishment of a worldwide quantum internet would provide individuals, businesses, organizations, and governments access to intrinsically secure communications. However, absorption of photons in transit between internet nodes can dramatically reduce the efficiency of such a quantum internet. Now a research group at Australia's (CQCCT) has invented a way to recover some of the lost quantum information by teleporting the original information to another photon.
