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

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that question sat at the heart of a famous disagreement between Albert Einstein and ...

New quantum experiments may settle the century-old Einstein vs Bohr debate, revealing key insights into quantum behaviour.

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

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks ...

It has been revealed that simply twisting and stacking two layers of oxide crystals can allow the atomic arrangement itself ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.
