Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
NPL, Dstl present potential 'billion global market' in quantum technologies
The Ministry of Defence's (MOD) Defence Science and Technology Laboratory (Dstl) will today present a number of research projects to bring to market the science behind the world's most accurate atomic clocks. ...
Researchers develop covert optical communication system
Light waves allow preferred bond breaking in symmetric molecules
An international team of scientists discovered a new quantum control mechanism to selectively shake and break C-H bonds in symmetric hydrocarbon molecules with the waveform of femtosecond laser pulses.
Probing the sound of a quantum dot
(Phys.org) —Physicists at the University of Sydney have discovered a method of using microwaves to probe the sounds of a quantum dot, a promising platform for building a quantum computer.
Ground-breaking insights into quantum chaos in ultracold gas
A specialised University of Innsbruck laboratory has successfully identified chaotic behaviour in atoms by using ultracold gas. This breakthrough could enable physicists to better understand the world of ...
Liquid spacetime: A very slippery superfluid, that's what spacetime could be like
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of ...
Quantum simulators developed to study inaccessible physical systems
Quantum simulators recreate the behaviour on a microscopic scale of biological and quantum systems and even of particles moving at the speed of light. The exact knowledge of these systems will lead to applications ranging ...
How to test the twin paradox without using a spaceship
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 ...
Philosopher untangles Einstein senility controversy
When it comes to looking at reality from the subatomic perspective of quantum theory, many physicists are nearly as much in the dark as the average person on the street.
Einstein's 'spooky' theory may lead to ultra-secure internet
(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.
Researchers see Kelvin wave on quantum 'tornado' for first time
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 ...
Scientists open a new window into quantum physics with superconductivity in LEDs
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining ...
Reviving Einstein's spooky action at a distance
Physicists at The University of Queensland and the Australian National University (ANU) have demonstrated a software-based quantum amplifier which has the potential to expand the use of ultra-secure quantum cryptographic ...
