Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

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 ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...
