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

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

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 ...
