Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

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 ...

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 ...

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, ...

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 ...

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 ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
