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.

Like the proverbial tree falling in the forest, scientists wonder: does reality exist on its own . . . or just when you ...

Scientists made an antimatter qubit made from an antiproton that is in a state of quantum superposition. This breakthrough ...

CERN scientists have analyzed a particle of antimatter isolated in an undecided quantum state known as a superposition for ...

Entangled particles are always in a correlated state. Consequently, if a property (such as spin) of one particle is measured, thus bringing it out of superposition, the same thing will also ...

It's time for the latest update in confirming things we already knew—and, as always, it's being far more interesting than you ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

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 ...

During a measurement, the superposition state is destroyed: the measurement forces the particle to decide in favour of one of the possible values. The Leggett-Garg inequality ...

They unveiled descriptions of duality (simultaneous wave-like and particle-like behaviors of electrons and photons), superposition (particles existing in multiple places at once), entanglement ...
