The tractor beam is a long-serving staple of sci-fi, but now Australian researchers have created a real-world version. While it won't exactly be capturing enemy spaceships anytime soon, the device can use light to pull in and trap atoms, which may be handy for quantum communications or memory systems...

Quantum entanglement – the idea that two particles can become inextricably linked across vast distances – is an eerie concept that Einstein himself had trouble accepting, and yet over the past few decades it's been experimentally demonstrated time and time again. But are there other variables interfering that we simply don't understand yet? To find out, MIT researchers have now performed a
With more sensitive data than ever being shared – and stolen – online, more secure connections are desperately needed. The answer could be a quantum internet, where information is passed almost instantaneously between nodes that have been quantum entangled, and are physically unhackable since any unauthorized observation of the data will scramble it. Researchers at Delft University of Tech
Full of antioxidants and vitamins, tea is pretty good for you, and green tea extracts have even been used as effective carriers for cancer drugs. New research led by Swansea University has found a novel way to wring more health benefits out of the stuff, by making quantum dots from tea leaves and using them to slow the growth of lung cancer cells...

To us living our lives on the macroscale, the tiny world of quantum mechanics seems weird and nonsensical. Take, for instance, quantum entanglement – the idea that two objects can become so entwined that changes to one can instantly affect the other, no matter how far apart they are. This has been regularly proven to be possible with atoms and molecules, but now scientists have managed to
Stealth technology may not be very stealthy in the future thanks to a US$2.7-million project by the Canadian Department of National Defence to develop a new quantum radar system. The project, led by Jonathan Baugh at the University of Waterloo's Institute for Quantum Computing (IQC), uses the phenomenon of quantum entanglement to eliminate heavy background noise, thereby defeating stealth
Researchers have come up with a way to generate truly random numbers using quantum mechanics. The method uses photons to generate a string of random ones and zeros, and leans on the laws of physics to prove that these strings are truly random, rather than merely posing as random. The researchers say their work could improve digital security and cryptography...Continue Reading Quantum spookine
Our universe has three spatial dimensions – or rather, three that our human senses can actively perceive. Some theories suggest there could be many more dimensions that we're unaware of, mostly because they're imperceptibly tiny. Now, Japanese researchers have taken the search for extra dimensions down to the nanoscale, using a neutron beam to study the gravitational force more precisely than
Ball lightning has been consistently reported for centuries, and yet we still know very little about it. Now, scientists at Amherst College and Aalto University have created quantum ball lightning by knotting together the magnetic spins of atoms, creating a quasiparticle that could help unlock the secrets of the strange phenomenon, or even make for more stable fusion reactors...Continue Readi
Humanity has been on the trail of the elusive and mysterious Majorana fermion since it was first theorized in 1937. Now, researchers at Chalmers University of Technology think they have manufactured a topological superconductor capable of hosting the mysterious particle. If so, this could be an important step towards practical and robust quantum computers which don't lose data...Continue Read is a social bookmarking place where you can share, find & discuss the best news around on most topics.
