The range of applications of this unique service, named 'QRBGS', spans fields as diverse as advanced scientific simulations, cryptographic data protection and security applications, as well as virtual entertainment – including online gambling and computer games.
'QRBGS' is an acronym for 'Quantum Random Bit Generator Service'. The service is based on 'Quantum Random Number Generator' – or QRBG for short – which is itself an innovative electronic device developed and built two years ago by RBI’s researchers. Overwhelming majority of other random number generators in use today don’t actually provide the 'true' random numbers, but instead so-called 'pseudo-random' numbers. They use various algorithms to pick the numbers from large pre-compiled databases of numbers obtained by e.g. rolling the dice. Hence, anyone who has access to such a database from which the pseudo-random number is picked, can accurately predict the next number that comes out of such generators. On the other hand, QRBG uses the inherently unpredictable quantum process of photon emission to generate random numbers, and as an output it provides the 'true’ random numbers which are impossible to predict.
The new RBI’s QRBGS service enables real-time internet access to QRGB device through several network access modes, such as C/C++ libraries, web services and Mathematica/Matlab client add-ons. The QRBG device itself is located and operated at the RBI and is connected to the internet through advanced computer technologies such as computer clusters and GRID networks. The use of QRBG service is free of charge for academic and scientific community.

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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,...
