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 quasistatic work cost derived by Landauer. This extra energy is dissipated as heat in the computer, inducing a fundamental limit on the speed of irreversible computers. We formulate a hardware-independent expression for this limit in the framework of stochastic processes. We derive a closed-form lower bound on…

It is proved analytically that it is possible to reset a bit with a work cost close to kBTln2 in a finite time, and an explicit protocol is constructed that achieves this, which involves thermalizing and changing the system's Hamiltonian so as to avoid quantum coherences.

A basic model of the memory is dealt with, a system including a particle making the Brownian motion in a time-dependent potential well, and it is shown that Landauer's claim holds rigorously if the random force acting on the particle is white and Gaussian, even if the potential is not static.

We consider the challenge of operating a reliable bit that can be rapidly erased. We find that both erasing and reliability times are non-monotonic in the underlying friction, leading to a trade-off…
