Abstract: Optimizing the performance of thermal machines is an essential task of thermodynamics. We here consider the optimization of information engines that convert information about the state of a system into work. We concretely introduce a generalized finite-time Carnot cycle for a quantum information engine and optimize its power output in the regime of low dissipation. We derive a general formula for its efficiency at maximum power valid for arbitrary working media. We further investigate the optimal performance of a qubit information engine subjected to weak energy measurements.

Informational Embodiment: Computational role of information structure in codes and robots [48.00447230721026]
We address an information theory (IT) account on how the precision of sensors, the accuracy of motors, their placement, the body geometry, shape the information structure in robots and computational codes. We envision the robot's body as a physical communication channel through which information is conveyed, in and out, despite intrinsic noise and material limitations. We introduce a special class of efficient codes used in IT that reached the Shannon limits in terms of information capacity for error correction and robustness against noise, and parsimony.

Quantum Information Engines: Assessing Time, Cost and Performance Criteria [0.0]
We investigate the crucial role of measurement time ($t_m$), information gain and energy consumption in information engines (IEs) As the measurement time increases, the information gain and subsequently the extracted work also increase. By considering the product of efficiency and power as a performance metric, we can identify the optimal operating conditions for the IE.

The problem of engines in statistical physics [62.997667081978825]
Engines are open systems that can generate work cyclically, at the expense of an external disequilibrium. Recent advances in the theory of open quantum systems point to a more realistic description of autonomous engines. We show how the external loading force and the thermal noise may be incorporated into the relevant equations of motion.

Recent predictions for quantum-mechanical enhancements in the operation of small heat engines have raised renewed interest. One essential question is whether collective effects may help to carry enhancements over larger scales.

We study a three-level quantum heat engine operating at maximum efficient power function. We find general expression for the efficiency and establish universal nature of efficiency at maximum power and maximum efficient power. We conclude by comparing the performance of our three-level quantum heat engine in maximum power and maximum efficient power regimes and show that the engine operating at maximum efficient power produces at least $88.89%$ of the maximum power output.
