Quantum mechanics is a pillar of modern science and technology, and has benefited the human society for a century. The wave function, also known as the quantum state, is the description of a quantum ...

Extremely cold atoms have been nudged to self-magnify their quantum states so they can be imaged in unprecedented detail. This could help researchers better understand what quantum particles do in odd ...

From the vantage point of quantum physics, the universe may in some ways be fundamentally unknowable. In quantum physics, every object, such as an electron, is matched to a mathematical formula called ...

Physicists recently mapped the hidden shape that underlies the quantum behaviors of a crystal, using a new method that’s expected to become ubiquitous. Famously, at the quantum scale, particles can be ...

Nearly a century after the development of quantum theories, a consensus has yet to emerge about what these theories tells us about ourselves and our places in the universe. Ney develops a framework — ...

The quantum physicists Sandu Popescu, Yakir Aharonov and Daniel Rohrlich have been troubled by the same scenario for three decades. It started when they wrote about a surprising wave phenomenon called ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
