Abstract: A quantum computing system includes a cryogenic chamber and an integrated circuit located in the chamber. The integrated circuit includes a substrate, a qubit formed on the substrate, and a dissipative element that is formed on the substrate and coupled to the qubit. When the qubit is tuned to a first flux value, the integrated circuit is enabled to perform quantum-computation operations on a set of quantum states of the qubit. The quantum states include a ground state and an excited state. When the qubit is tuned to a second flux value, the qubit is enabled to transfer energy associated with the excited state from the qubit to the dissipative element. Upon the energy transfer, the qubit is transitioned to the ground state. The dissipative element is enabled to dissipate the transferred energy to a portion of the substrate.
