This computer-generated visualization shows the wavelike pattern of a “quantum handshake” between a hydrogen atom emitting energy and another atom receiving the energy. (J. Cramer and C. Mead via ...

A team of scientists recently conducted an exciting quantum physics experiment allowing them to demonstrate that reality might actually be real. Well, don’t everybody applaud all at once. It’s ...

When we measure a qubit in superposition, it picks one state, like a spinning coin landing heads or tails. This is called ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

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 ...

Quantum mechanics, when examined closely, poses some deep questions about reality. These questions often take the form of thought experiments, which are later (usually much later) followed up by real ...

IN THE minuscule realm of atoms and particles, it looks as though things exist not so much as things at all, but as vague clouds of possibilities. They seem to be here, there and everywhere, or appear ...
