Abstract

A method and apparatus for sending encrypted data across a node in a communications network. In one illustrative embodiment, an apparatus comprises a first communicator, a second communicator, and a number of nodes. The first communicator is configured to encrypt unencrypted data to form the encrypted data using a first quantum key distributor. The second communicator is configured to decrypt the encrypted data using a second quantum key distributor. The number of nodes is configured to receive the encrypted data sent from the first communicator and send the encrypted data to the second communicator using quantum teleportation. The encrypted data remains encrypted as the encrypted data passes through each of the number of nodes.
