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.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
