Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in some fields and settings. The so-called spin (i.e., intrinsic angular ...

Quantum computers and communication devices work by encoding information into individual or entangled photons, enabling data to be quantum securely transmitted and manipulated exponentially faster ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

(Nanowerk News) Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown (Science Advances, "Field ...

Although elusive, the quantum spin has led to some of the deepest insights we now know. Quantum mechanics has a lot of weird stuff - but there are things that everyone agrees that no one understands.

New spin on topology: spin guided light scattering has been observed in a liquid crystal (Courtesy: Shutterstock/Serg-DAV) Just as topological insulators provide protection to electrons travelling ...

A team of Harvard physicists published an article Wednesday outlining a novel method for determining the “spin” — or angular momentum — of a black hole. The paper appeared in Physical Review D, a peer ...

Quantum researchers have demonstrated a method for encoding vastly more information into a single photon, opening the door to even faster and more powerful quantum communication tools. Quantum ...
