Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Sigmund (Games of Life), a professor emeritus of mathematics at the University of Vienna, explores in this spirited study the ways that math has been used to make sense of the world, from abstract ...

Quantum entanglement is the key to quantum computing, cryptography, and numerous other real-world applications of quantum mechanics. It is also one of the strangest phenomena in the Universe, ...

When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what ...

Scientists on the ATLAS collaboration performed the highest-energy measurement of quantum entanglement. On the smallest level, the universe operates in such a bizarre way that even Albert Einstein had ...

A couple of weeks before last Halloween, physicists in the Netherlands treated the physics world with experimental proof of what Einstein called “spooky action at a distance.” It’s not the first time ...

Precise parameter estimation plays a central role in science and technology. The statistical error in estimation can be decreased by repeating measurement, leading to ...
