Abstract
Systems and methods for operating a quantum Otto cycle, including a superconducting LC resonator circuit electrically coupled to an input control unit with a reservoir source and a waveform generator configured to generate a bias current. A superconducting flux qubit is coupled to the LC resonator via a superconducting quantum interference device (“SQUID”). The SQUID generates a flux in the presence of the bias current, and the flux generated by the SQUID mediates a coupling rate between the flux qubit and the LC resonator. The waveform generator alternates the bias current to adiabatically change the coupling rate between the flux qubit and the LC resonator during adiabatic stages of the quantum Otto cycle. The reservoir source sends pulses to thermalize the flux qubit and the LC resonator system during isochoric stages of the quantum Otto cycle.
