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 ...
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Teleportation with engineered quantum systems
A team of University of Queensland physicists has transmitted an atom from one location to another inside an electronic chip.
Light particles illuminate the vacuum
Researchers from the Finnish Aalto University and the Technical Research Centre of Finland succeeded in showing experimentally that vacuum has properties not previously observed. According to the laws of ...
Research team challenges the limits of famous quantum principle
(Phys.org) —A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
D-Wave chip passes rigorous tests
With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended.
'Quantum Internet': Towards realization of solid-state quantum network
(Phys.org) —Researchers at TU Delft in the Netherlands have managed to bring two electrons, three meters from each other, into a quantum- entangled state. This result marks a major step towards realizing ...
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.
Black holes do not exist as we thought they did
On January 24, the journal Nature published an article entitled "There are no black holes." It doesn't take much to spark controversy in the world of physics... But what does this really mean? In a brief ...
Researchers demonstrate Heisenberg uncertainty principle at macro level
Never mind the noise: Quantum entanglement allows channel information rate to exceed Shannon zero-error capacity
Researchers propose using distant quasars to test Bell's theorem
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 vio ...
Can an oil bath solve the mysteries of the quantum world?
For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behaviour. What sounds like a high-school experiment has in fact provided the first ever ...
