Aren’t we tired enough of continuously recharging the battery of mobile phones?
Starts tomorrow in Aalborg (DK) the International conference ICT-Energy 2016 on “energy efficiency and sustainability in ICT”. The conference is organized by prof. K. Larsen, at the University of Aalborg, in the framework of the project “ICT-Energy” funded by European Commission.
The goal of the conference is to bring together scientists from the vast international community interested in the way ICT (Information and Communication Technology) devices consume energy during functioning.
In fact, reducing energy consumption in 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 present systems. On the other hand: aren’t we tired enough of continuously recharging the battery of mobile phones?
The European project ICT-Energy, coordinated by Luca Gammaitoni at the university of Perugia (IT), targets energy consumption in computing and communication, with the aim of raising awareness and promoting actions for the sustainable development of the future of the entire ICT sector.
During the conference there will be oral presentations on a number of innovative solutions, at the edge of present research, for the future of computing. Particularly, two of the most revolutionary solutions in this field (single electron transistors and micro mechanical switches) will be presented by the people who designed them (F. Gonzalez-Zalba from Hitachi Cambridge and M. Lopez-Suarez from NiPS Laboratory). Proceedings of the conference are published in a special number of ICT-Energy Letters, freely available here: www.ict-energyletters.eu.
The Science Conference is supported by European Commission under the FET Proactive Coordination Action ICT-Energy (www.ict-energy.eu).
Future quantum computers might not be all that different from the one you're using now. An international team of researchers have created a the most fundamental part of a quantum computer—the quantum bit, or qubit—using only a CMOS transistor that is not much different from those in today's microprocessors.
Scientists from the TOLOP consortium have demonstrated a new hybrid system that is a promising candidate as a building block for quantum computation, showing a way to couple a natural phosphorus
atom with an artificial atom called a quantum dot.
The research, published recently in the journal Physical Review X (“Charge Dynamics and Spin Blockade in a Hybrid Double Quantum Dot in Silicon”), is a first step to using the new ‘hybrid’ system as a way to transport quantum information, encoded in the form of the fundamental property of an electron called its spin, over larger distances.
A Spanish-led team of European researchers at the University of Cambridge has created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the ‘gate sensor’ and could be applied in quantum computers of the future to read information stored in the charge or spin of a single electron.
The conference is jointly organized by the FP7 FET EC projects MULTI (multivalued and parallel computing at the molecular scale) and TOLOP (low power information processing in solid state devices). Several topics related to CMOS technology as well as the implementation of complex logic operations in molecular media will be covered:< >emerging steep switch devices & CMOS technologiesissues related to the energy-dissipation of CMOS devices and circuitsoptical addressing of molecular machines through state-of-the-art nonlinear ultrafast optical techniqueselectrical and optical addressing of atomic and molecular states in the solid-statecomplex DNA-based biomolecular architectures for complex logic operationsDownaload the invitation (PDF, 160kB)
Several high-fidelity qubit implementations in silicon have been demonstrated over the last few years. But now, researchers in the field of Silicon Quantum Information Processing are faced with the challenge of upscaling these technologies to a meaningful number of qubits. In the short term, it is necessary to realise two-qubit and multi-qubit structures and only with a strong collaboration with industrial silicon fabrication platforms this endeavour will be achievable. The meeting aims to bring together researchers interested in silicon-based quantum technologies with academic and industrial experts from silicon device fabrication facilities. The meeting will focus on bridging the gap between basic research on single-qubit structures and the large scale integration possibilities of industrial silicon fabrication plants. The topics covered during the meeting will range from recent studies on single qubits to scalable multi-qubit proposals through enabling fabrication technologies. On the single qubit side, we will explore experimental and theoretical studies on qubit design, measurement and control with special emphasis on scalable architectures. On the multiple qubit side, we will focus on theoretical proposals for large scale integration and multi qubit control protocols. Finally, nanofabrication experts on CMOS-based technologies and atomic scale lithography will give their views on how to implement this change in paradigm: from one to many qubits.
