Abstract
A system that includes a quantum key device, a first device, and a second device. A monitor module is configured to detect, at the first device, that the second device is reading quantum information over a second quantum communication channel. A read module is configured to read, at the first device, the quantum information over a first quantum communication channel. An encryption module is configured to generate a first quantum encryption key at the first device using the quantum information that is read over the first quantum communication channel. The encryption module is also configured to encrypt data using the first quantum encryption key to create encrypted data. The second device decrypts the encrypted data using a second quantum encryption key generated at the second device using the quantum information read at the second device to create decrypted data.
