A measurement-driven quantum engine using a damped oscillator as the demon's pointer can simultaneously reach high power and efficiency and operates beyond the Otto window when the pointer states are distinguishable.
the qubit is excited and the field is able to extract a positive net energy from it

Maxwell's lesser demon: a quantum engine driven by pointer measurements
A measurement-driven quantum engine using a damped oscillator as the demon's pointer can simultaneously reach high power and efficiency and operates beyond the Otto window when the pointer states are distinguishable.
