A simple device measures the quantum noise of vacuum fluctuations and generates true random numbers Behind every coincidence lies a plan - in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be explained in mathematical terms. Researchers at the Max Planck Institute for the Physics of Light in Erlangen have constructed a device that works on the principle of true randomness. With the help of quantum...

International collaboration tackles the problem The Norwegian University of Science and Technology (NTNU) and the University of Erlangen-Nrnberg together with the Max Planck Institute for the Science of Light in Erlangen have recently developed and tested a technique exploiting imperfections in quantum cryptography systems to implement an attack. Countermeasures were also implemented within an ongoing collaboration with leading manufacturer ID Quantique. Quantum cryptography is a technology...

Max Planck physicists develop an experiment to investigate the random motion of quantum particles Life would sometimes be so much easier if we were quantum particles. For example, if we were trying to find our way out of a strange town allowing chance telling us which way to go at every intersection. As objects of classical physics, this would mean becoming more and more lost in the center of the road network. If we were particles that obeyed the laws of quantum mechanics, we would sooner or...

  • A stinking tobacco.
  • Offal; waste animal product; organic matter unfit for consumption.
This word comes from the Spanish 'mondongo,' tripe, entrails.
