The canton of Geneva became a world pioneer when it decided to use quantum cryptography to protect the dedicated line used for counting votes in the October national elections. The world’s first commercial quantum random number generator and quantum cryptography system was developed by the Swiss company id Quantique – a spin-off company of the University of Geneva – so the choice of Geneva to test the system in action was only appropriate.
The firm was founded in 2001 by four researchers from the University of Geneva: Nicolas Gisin, Grégoire Ribordy, Olivier Guinnard and Hugo Zbinden. According to Gisin: “Protection of the federal elections is of historical importance in the sense that, after several years of development and experimentation, this will be the first use of a 1 GHz quantum encrypter, which is transparent for the user, and an ordinary fibre-optic line to send data endowed with relevance and purpose. So this occasion marks quantum technology’s real-world début.”All about Eve
The use of the system developed by id Quantique makes it possible to detect Eve’s presence almost immediately and to take counter measures. The system works, however, not only when there is an eavesdropper on the line but also when data become corrupted accidentally. Which, in the case of the Swiss elections, is an equally important feature.
For Robert Hensler, the Geneva State Chancellor, the application of quantum cryptography will go a long way towards alleviating concerns over eVoting. “In this context, the value added by quantum cryptography concerns not so much protection from outside attempts to interfere as the ability to verify that the data have not been corrupted in transit between entry and storage,” he is quoted as saying.SwissQuantum, a new standard for data security
The project’s plans, however, extend beyond the Geneva region with a longer-term view of expanding the network throughout the country and beyond. This technology will appeal in particular to certain core industries of the economy which depend particularly on data security – banks, insurance companies, high-tech businesses,… In this regard, it is hoped that the SwissQuantum name will come to be seen as the best guarantee for reassuring potential clients of the soundness of this scientific innovation.
id Quantique is a partner in the European project SECOQC which began in April 2004. “The SECOQC project makes it possible for id Quantique’s engineers to interact with some of the best groups worldwide in the field of quantum cryptography,” observes Ribordy. Together, the project partners intend to lay the foundations for a long-range, high-security communication network that combines the entirely novel technology of quantum key distribution with components of classical computer science and cryptography.
Ensuring effective data security is the next challenge for global data networks. SECOCQ will provide European citizens, companies and institutions with a tool that allows them to face the threats of future interception technologies, thus creating significant advantages for the European economy.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
