Abstract
Embodiments of feedback-based quantum circuits are described. Embodiments of such quantum circuits may be externally controlled using only basis or eigenstate (classically-observable) signals without triggering de-coherence. Additionally, embodiments of such quantum circuits allow the internal (superpositioned) quantum state information to be preserved over long periods of time and present options for quantum error-correction due to the basis-state controls. Moreover, a coupling of two such feedback-based quantum circuits allows for quantum-channel-based information exchange to a variety of ends.
