Systems and apparatus related to quantum resonance interferometry for detecting signals are described. First and second signals are received and coupled with a first function and a second function, respectively, generated from a first quantum mechanical system and a second quantum mechanical system, respectively. By doing so, a first tunneling rate and a second tunneling rate are generated. The first tunneling rate is coupled with a third function generated from a third quantum mechanical system. The second tunneling rate is coupled with the third function to obtain a third tunneling rate. Upon determining that the third tunneling rate is greater than a threshold, it is identified that the second signal corresponds to the first signal.
