A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

A restless state, known as a quantum spin liquid, could unlock new kinds of particles and serve as a foundation for quantum ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different ...

Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far ...

Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states exist in ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in ...

Researchers in Germany have created a new photonic chip that precisely controls quantum light without disrupting fragile signals.
