Is stochastic thermodynamics the key to understanding the energy costs of computation?

Article Synopsis
- The relationship between thermodynamics and computation has fascinated scientists since the 19th century, but its significance has grown due to the rising energy costs of digital devices.
- Real-world computers, including biological ones like brains, operate under various physical constraints, which impact their thermodynamic dynamics and efficiency.
- The emerging field of stochastic thermodynamics offers new analytical techniques to explore how these constraints affect the fundamental thermodynamic properties of systems performing computation.
Robots have components that work together to accomplish a task. Colloids are particles, usually less than 100 µm, that are small enough that they do not settle out of solution. Colloidal robots are particles capable of functions such as sensing, computation, communication, locomotion and energy management that are all controlled by the particle itself.

The videos will be used by physicians to perform remote analysis and follow-up routine of prenatal examinations of pregnant women. Two open source simulators (the ONE and NS-2) were used to evaluate the results obtained utilizing a CoDPON (continuous displacement plan oriented network).
