Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

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

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

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...
