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.
Universal bounds on observable precision in non-Markovian open quantum systems are derived via an asymmetry term for forward-backward disparity and a generalized activity term for environmental changes.
