The cost of remembering

 

Perugia, May 8, 2018

 

Published online the new paper on the "Cost of remembering" from NiPS.
The paper, published on Physycal Review A, deals with the fundamental energy limits associated with preserving a single bit of information.

The good news is that, if you operate fast enough and/or carefully enough, you can get away with a negligible energy cost.
The bad news is that no memory can last forever...

Published today on Nature Communications the results of an experiment at NiPS Lab, in Perugia, Italy. They show that irreversible logic gates can be operated below the Landauer’s limit.
 

 

New paper from the Landauer project on the cover of Nanotechnology

 

 

Perugia, 15 June, 2016

A novel paper by P Pfeffer, F Hartmann, I Neri, A Schade, M Emmerling, M Kamp, L Gammaitoni, S Höfling and L Worschech entitled "Half adder capabilities of a coupled quantum dot device” is on the cover of Nanotechnology, Volume 27, Number 21.

The paper is the product of a collaboration between the Wuerzburg Group and NiPS, in the framework of the Landauer project (www.landauer-project.eu).

The abstract of the paper: 

In this paper we demonstrate two realizations of a half adder based on a voltage-rectifying mechanism involving two Coulomb-coupled quantum dots. First, we examine the ranges of operation of the half adder's individual elements, the AND and XOR gates, for a single rectifying device. It allows a switching between the two gates by a control voltage and thus enables a clocked half adder operation. The logic gates are shown to be reliably operative in a broad noise amplitude range with negligible error probabilities. Subsequently, we study the implementation of the half adder in a combined double-device consisting of two individually tunable rectifiers. We show that this double device allows a simultaneous operation of both relevant gates at once. The presented devices draw their power solely from electronic fluctuations and are therefore an advancement in the field of energy efficient and autonomous electronics.

 

 

 

 

Towards zero-power ICT. New review article from NiPS

 

 

Is it possible to operate a computing device with zero energy expenditure? This question, once considered just an academic dilemma, has recently become strategic for the future of information and communication technology.
