Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a ...

Quantum superposition describes how a quantum particle, like an electron, a photon, or even an atom, can exist in multiple different states at the same time — until it's measured.

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed.

Quantum superposition is not just a property of subatomic particles but also of the most massive objects in the universe. That is the conclusion of four theoretical physicists in Australia and Canada ...

The coin example is superposition of two results in one place. As a simple example of entanglement (superposition of two separate places), it could be a photon encountering a 50-50 splitter.

Quantum superposition is the idea that particles exist in multiple states at once. When a measurement is performed, it is as if the particle selects one of the states in the superposition.

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

The spookiness of quantum entanglement emerges from the reality of quantum superposition, and was clear to the founding fathers of quantum mechanics who developed the theory in the 1920s and 1930s. To ...

On a quiet pandemic afternoon in 2021, Zhiyuan Wang, then a graduate student at Rice University, was alleviating his boredom by working on a weird mathematical problem.After he found an exotic ...
