Brownian Computation Is Thermodynamically Irreversible
The thermodynamics of computation applies ideas from thermal and statistical physics to physical devices implementing computations. Its major focus has been to characterize the principled limits to thermal dissipation in these devices. The best case of no dissipation arises when we use processes that create no thermodynamic entropy. They are thermodynamically reversible processes in which all d...
متن کاملThermodynamically Favorable Computation via Tile Self-assembly
The recently introduced Thermodynamic Binding Networks (TBN) model was developed with the purpose of studying self-assembling systems by focusing on their thermodynamically favorable final states, and ignoring the kinetic pathways through which they evolve. The model was intentionally developed to abstract away not only the notion of time, but also the constraints of geometry. Collections of mo...
متن کاملOn Brownian computation
as a way of demonstrating that logically reversible mathematical operations can be computed by physical processes that are thermodynamically reversible, or nearly so. In a recent paper 4 , I have argued that the computational processes they describe are not thermodynamically reversible and that their misidentification rested on a misapplication of thermal and statistical physics. A question lef...
متن کاملReversible Simulation of Irreversible Computation
Computer computations are generally irreversible while the laws of physics are reversible. This mismatch is penalized by among other things generating excess thermic entropy in the computation. Computing performance has improved to the extent that eeciency degrades unless all algorithms are executed reversibly, for example by a universal reversible simulation of irreversible computations. All k...
متن کاملIs protein turnover thermodynamically controlled?
A parametric correlation (p less than 0.01) has been found between the in vitro thermal stability and in vivo turnover rates of nine intracellular proteins. These results are discussed in terms of a "thermodynamic" model for turnover control, in which the rate of intracellular protein degradation is controlled by intramolecular conformation equilibria. A peculiar exception is provided by glycer...
