The stochastic thermodynamics of computation
DH Wolpert - Journal of Physics A: Mathematical and Theoretical, 2019 - iopscience.iop.org
One of the central concerns of computer science is how the resources needed to perform a
given computation depend on that computation. Moreover, one of the major resource …

Finite-time quantum Landauer principle and quantum coherence
The Landauer principle states that any logically irreversible information processing must be
accompanied by dissipation into the environment. In this Letter, we investigate the heat …

Finite-time Landauer principle
We study the thermodynamic cost associated with the erasure of one bit of information over
a finite amount of time. We present a general framework for minimizing the average work …

Information and thermodynamics: Fast and precise approach to landauer's bound in an underdamped micromechanical oscillator
The Landauer principle states that at least k BT ln 2 of energy is required to erase a 1-bit
memory, with k BT the thermal energy of the system. We study the effects of inertia on this …

Universal bound on energy cost of bit reset in finite time
We consider how the energy cost of bit reset scales with the time duration of the protocol. Bit
reset necessarily takes place in finite time, where there is an extra penalty on top of the …

Work, entropy production, and thermodynamics of information under protocol constraints
A Kolchinsky, DH Wolpert - Physical Review X, 2021 - APS
In many real-world situations, there are constraints on the ways in which a physical system
can be manipulated. We investigate the entropy production (EP) and extractable work …
