Abstract
A system that comprises a quantum key device configured to generate quantum information and transmit the quantum information over a first and second quantum communication channel. The system also comprises a first device, communicatively coupled to the quantum key device over the first quantum communication channel, and a second device, communicatively coupled to the quantum key device over the second quantum communication channel. The system further comprises an encryption module configured to encrypt data to create encrypted data, at the first device, using a first quantum encryption key. The system also comprises a decryption module configured to decrypt the encrypted data to create decrypted data, at the second device, using a second quantum encryption key. The first quantum encryption key is the same as the second quantum encryption key. The system further comprises a termination module configured to prevent access to the decrypted data after a predetermined period of time.
