Igor Neri (right in the picture) and Luca Gammaitoni (left in the picture) represented NiPS at the kick off meeting of the new European project OPRECOMP.
OPRECOM is is a 4-year research project co-funded under the EU 7th Framework Horizon 2020 – Re Program Future and Emerging Technologies (FET) Proactive Initiative: emerging themes and communities. FET aims to go beyond the conventional boundaries of ICT and ventures into uncharted areas, often inspired by and in close collaboration with other scientific disciplines.
OPRECOMP aims to build an innovative, reliable foundation for computing based on transprecision analytics.

Miquel López-Suárez, from NiPS, received his PhD special prize award for his theses "Non-linear Nanoelectromechanical Systems for Energy Harvesting".
The PhD special prizes confer value to theses which have received the qualification of excellence "Cum Laude" and which, having been proposed by the Admissions Committee of each academic programme, stand out for their contribution and advance in the different areas of that University.
The cerimony was held at the Hotel Campusof the Universitat Autònoma de Barcelona on November the 18th of 2016.

Research recently published on Nature Communications shows that traditional logic gates, used in present computers, could be operated without minimum energy dissipation.
Reducing energy consumption in Information and Communication Technology (ICT) devices has nowadays become a strategic task to further improve performances and diffusion of such technology. Both the future of supercomputing and the dawn of the Internet-of-Things scenario are at risk if the power consumption problem is not solved: too much electric energy is required by ICT devices. On the other hand: aren’t we tired enough of continuously recharging the battery of mobile phones?
To complicate things, the continuous improvement in the efficiency (number of operation per Watt) of computing devices over the years has finally brought the technology close to what was supposed to be a fundamental limit of physics: the so-called Landauer’s limit.
An experiment at NiPS Lab, in Perugia (Italy) shows that a traditional logic gate could, in principle, be operated below the Landauer’s limit and thus the supposed minimum energy expenditure for operating traditional logic gates, does not exist. A good news for those interested in further improving energy efficiency in ICT.
The results of this experiment made by the scientists of NiPS Laboratory, led by Prof. Luca Gammaitoni, at the University of Perugia, published on Nature Communications on 28th June 2016, will be presented in the next few weeks at two international conferences: the ICT-Energy Science conference in Aalborg (DK) on Aug. 17th by Miquel Lopez-Suarez and the ICAND 2016 conference in Denver (CO) on Aug. 29 by L. Gammaitoni.

The phenomenon of Stochastic Resonance, proposed for the first time in 1981 (R. Benzi, S, Sutera, A. Vulpiani, J. Phys. A 14, L453, 1981; C. Nicolis, G. Nicolis, Tellus 33, 225, 1981) has attracted continuous attention in the last 30 years. Most of its fortune among scientists and the public at large is due to its counter-intuitive characteristic: given a non-linear dynamic system, the degree of order in its behavior can be increased simply by injecting more noise, i.e. increasing the disorder. Clearly what triggered researchers’ curiosity the most was the suggestion that noise, often considered a nuisance of small influence, can play instead a very significant role with potential applications to biological systems and technological devices.
In 1998 an international team of scientists wrote the most comprehensive and, to date, the most appreciated review article to describe this phenomenon:

Authors: GAMMAITONI, L; HANGGI, P; JUNG, P; MARCHESONI, F.
Journal: REVIEWS OF MODERN PHYSICS Volume: 70 Issue: 1 Pages: 223-287 Published: 1998
Since then the review article has grown to become a highly cited paper that has recently reached 5,000 citations on Google Scholar (3,745 on ISI).

Towards quantum computing using silicon-on-insulator transistor technology
Silicon complementary metal oxide semiconductor (CMOS) technology has driven the
success of the semiconductor industry in the last few decades. The classical computational
power has increased exponentially but this progress is bound to reach its fundamental limits
in the next years. We are now starting to see that CMOS technology itself can offer an
alternative to overcome its classical fundamental limits, not in
ation. A quantum computer promises to be exponentially more efficient than classical
computers in solving a specific set of problems, such as database searches and prime
