Quantum secure communication systems communicate quantum signals for quantum key distribution and classical signals with encrypted data and commands via a single optical fiber. In some systems, the single fiber carries classical data in both directions along with quantum communications. For example, quantum keys can be used to encrypt packets for bidirectional communication between two parties. In other systems, a single fiber is used for one way classical communications and quantum communications. The communication systems are secured using a security parameter based on the quantum and classical communications across the optical fiber.
