A quantum Zeno dynamics protocol confines the evolution of a finite-time Otto-cycle quantum heat engine to a subspace that preserves instantaneous energy populations, recovering quasistatic efficiency with added thermodynamic costs from monitoring and switching.
Estimates energetic costs of QFT on trapped-ion QC from experimental data and scaling arguments, finding a possible energetic advantage threshold lower than the computational time advantage threshold.
