Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin paradox".
(Phys.org) —Einstein's scepticism about quantum mechanics may lead to an ultra-secure internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.
A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process called reconnection. ...
With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended.
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if violated by experiments, ...
The massive release of the US National Security Agency (NSA)'s classified documents by Edward Snowden continues to raise questions about security.
(Phys.org) —A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
By using an ultrafast camera, scientists say they have observed the very first instants following the absorption of light into artificial yet organic nanostructures and found that charges not only formed rapidly but also ...
