Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...
Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

A quantum discovery that breaks the rules of heating
In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new quantum experiment suggests that this rule is not absolute, revealing a ...
A team of physicists has reimagined one of science's most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...
Electrons are influenced by a magnetic field display known as the quantum Hall effect (QHE), which helps scientists make hyper-accurate measurements. Now, scientists have observed a similar behavior ...
Led by quantum industry pioneers, the startup aims to overcome challenges in qubit yield and component integration using ...
Special relativity could be harnessed to build a novel quantum computer, and creating it this way could let us use machine learning to deepen our understanding of the quantum realm. Albert Einstein’s ...

Quantum computers could expose our digital secrets – but there are much better reasons to build them
Quantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum mechanics, the set of rules governing how physics operates at atomic and ...
Quantum physics describes matter and light in terms of discrete quanta and inherently probabilistic rules that depart from classical intuition. At its heart lie wave–particle duality—entities such as ...
