Albert Einstein was right about a shocking among of things, but not necessarily everything.

Scientists developed a two-photon-enhanced metasurface that cuts photon requirements for nanoscale displacement measurement ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...
