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.
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 ...
Simulating time travel: Doctor Who meets Professor Heisenberg
(Phys.org)—University of Queensland researchers have simulated time travel using light particles. Lead author and PhD student Martin Ringbauer, from UQ's School of Mathematics and Physics, said the study ...
Time warp: Researchers show possibility of cloning quantum information from the past
(Phys.org) —Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU's Mark ...
Scientists cast doubt on renowned uncertainty principle
Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure ...
Large-scale quantum chip validated
A team of scientists at USC has verified that quantum effects are indeed at play in the first commercial quantum optimization processor.

Curtains down for the black hole firewall paradox: Making gravity safe for Einstein again
Research by scientists at the University of York has revealed new insights into the life and death of black holes.
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 ...
