Patent ID: 8294138

Claim:
A quantum computing system, comprising: a transmission line having an input port and an output port, and configured to transmit a signal having a frequency; and a superconducting qubit configured to receive an input pulse and to occupy a first state |0 , and a second state, |1 , the superconducting qubit coupled to the transmission line, the superconducting qubit having a resonance frequency at the output port of the transmission line, wherein the resonance frequency can be one of two distinct values, a distinct first value corresponding to a first quantum well, and a second distinct value corresponding to a second quantum well, wherein if the resonant frequency is equal to the first value, then the qubit occupies the state |0 prior to applying the input pulse and the state |0 remained in the first quantum well after applying the input pulse, and if the resonant frequency is equal to the second value, then the qubit occupies the state |1 prior to applying the input pulse and the state |1 tunneled to the second quantum well subsequent to applying the input pulse.
