Abstract:We present a simultaneous-cooling protocol for a double-resonator system via projective measurements on an ancillary V -type qutrit. Through repeated measurements on the ground state of the ancillary system, the two resonators can be cooled down to their respective ground states from thermal states. With respect to the measurement-based cooling, an optimized measurement-interval τopt is analytically obtained for the first time, which is inversely proportional to the collective thermal Rabi frequency Ω th as a … Show more
