What do you mean with quantum encryption? QKD (Quantum Key Distribution)?

Though the concept seems nice, it has quite a few issues in practice. Such as distance between coupled devices, and the need to have a dedicated physical communication line.

Oh and before you think you can just chain several devices to get longer distances: this opens you up to classical MitM attacks.
