‘The dark side’ of quantum computers

Public Release: 13-Sep-2017   Eindhoven University of Technology The era of fully fledged quantum computers threatens to destroy internet security as we know it. Researchers are in a race against time to prepare new cryptographic techniques before the arrival of quantum computers, as cryptographers Tanja Lange (Eindhoven University of Technology, the Netherlands) and Daniel J.…

The world’s most powerful X-ray laser beam creates ‘molecular black hole’

Public Release: 8-Jun-2017   DOE/Argonne National Laboratory   Caption A team of researchers, including several physicists from the US Department of Energy’s Argonne National Laboratory, discovered that a molecule containing a large atom could act like a molecular ‘black hole’ when exposed to ultrafast laser pulses, sucking in electrons from nearby lighter atoms.

Study reveals evidence that the universe is a hologram

Public Release: 30-Jan-2017   University of Waterloo The first observational evidence that the universe could be a hologram has been published in the journal Physical Review Letters. The international study may lead to new beliefs on the Big Bang Theory and on quantum gravity, one of theoretical physics’ most profound problems. Researchers from the University…

Everything is immortal "The cup is now found at any and every time,” ‘T violation’

Public Release: 17-Aug-2016 How we escaped from the Big Bang Griffith’s theory on moving through time Griffith University Associate Professor Dr Joan Vaccaro, of Griffith’s Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called ‘T violation’ could be the origin of time evolution and conservation laws.…

Weird quantum effects stretch across hundreds of miles

Public Release: 19-Jul-2016   Massachusetts Institute of Technology CAMBRIDGE, Mass. — In the world of quantum, infinitesimally small particles, weird and often logic-defying behaviors abound. Perhaps the strangest of these is the idea of superposition, in which objects can exist simultaneously in two or more seemingly counterintuitive states. For example, according to the laws of…

Schrödinger’s cat is alive and dead in 2 places at once

PUBLIC RELEASE: 26-MAY-2016   AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE Through new experiments involving the famous Schrödinger cat state paradox, researchers have shown that a “quantum cat” can be both alive and dead, and in two places at once. The results, which involve inducing a large number of photons to have matching states (or…

Computing a secret, unbreakable key

Public Release: 20-May-2016   Researchers develop the first available software to evaluate the security of any protocol for Quantum Key Distribution University of Waterloo What once took months by some of the world’s leading scientists can now be done in seconds by undergraduate students thanks to software developed at the University of Waterloo’s Institute for…

Are humans the new supercomputer?

Public Release: 13-Apr-2016   Today, people of all backgrounds can contribute to solving serious scientific problems by playing computer games. A Danish research group has extended the limits of quantum physics calculations and simultaneously blurred the boundaries between man and mac Aarhus University The saying of philosopher René Descartes of what makes humans unique is…

Quantum knots are real!

Public Release: 19-Jan-2016   Aalto University IMAGE: Visualization of the structure of the created quantum knot. Each colorful band represents a set of nearby directions of the quantum field that is knotted. Note that each band is twisted and linked with the others once. Untying the knot requires the bands to separate, which is not…

Swedish researchers reveal quantum security hole

“They found that energy-time entanglement – the method that today forms the basis for many systems of quantum cryptography – is vulnerable to attack.” Public Release: 18-Dec-2015   Hacking the Bell Test using classical light in energy-time entanglement-based quantum key distribution Linköping University Quantum cryptography is considered a fully secure encryption method, but researchers from…

Is the universe a hologram?

Public Release: 27-Apr-2015 Describing the universe requires fewer dimensions than we might think; new calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself Vienna University of Technology   IMAGE: Is our universe a hologram?
