Physicists have put thousands of atoms into a "Schrödinger's cat" state — smashing the record for the most macroscopic object to be observed in a quantum state. In a new study, researchers observed ...

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a stringent test of quantum mechanics. Matter wave in the spotlight: The image ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also have wave-like properties. These properties can be represented using the wave ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

In a paper published in Nature Photonics, the research team from the Center for Quantum Information and Communication – Ecole polytechnique de Bruxelles of Université libre de Bruxelles, has found an ...

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...
