From: An autonomous quantum machine to measure the thermodynamic arrow of time
Deviation from the integral fluctuation theorem a and mean entropy production b for the complete autonomous machine. Parameters: ω0/2π = 2 THz (amounts to ħω0/kBT = 1.2 for T = 80 K used in Fig. 2), Ω/2π = 100 kHz, γ/Ω = 5, gm/Ω = 10 and |β0| = 5000. In both cases, two different expressions were used. The blue dots are computed using the final distribution of mechanical states \(\left\{ {\left| {\beta _{\mathrm{\Sigma }}\left( {t_N} \right)} \right\rangle } \right\}\) and mimic an experiment. The red squares involve the probability of the reversed trajectory, which can only be the result of a theoretical treatment. (See Methods for more details.)
