Once cooled, the laser light has to give the bead a bit of a kick in just the right way to entangle the two. This is done by ...

Magic tricks reveal how the brain forms reality, as a review of 55 studies explores gaps in attention, perception and ...

Pairs of photons provide a gentle way to measure the impact of a molecule’s environment on its ultrafast dynamics.

Scientists at the Raman Research Institute measured a quantum measure of 1.17 using photons. The result shows that Quantum Measure Theory can be tested in a laboratory without overturning ordinary ...

A device that can detect particles arriving from space does not necessarily require a multimillion-dollar laboratory. A compact detector developed by physicist Spencer Axani began as a low-cost ...

Light exhibits some of the strangest properties in our cosmos. It manifests as both a wave and a particle, and its speed in a vacuum is invariant. While physicists now fully grasp the way light ...

For most objects, for every action, there is an equal and opposite reaction. But if you are swimming upstream in a river of quantum light, the normal rules don’t apply. Physicists have demonstrated ...

A crystal with special geometric properties can be optically driven to produce an output beam with any desired polarization. Researchers have developed a method for controlling the polarization of ...

Shrinking Young’s experiment (a) The classical double-slit experiment using light (slit spacing ~1 mm, propagation distance ~1 m). (b) Schematic of atomic-scale interference in which a pair of ...

In an experiment deep underground, a tiny flash of light may, ironically, mark the first detection of dark matter. This mysterious stuff should outnumber regular matter by a ratio of 5 to 1, but ...

LUX-ZEPLIN, an experiment co-led by Brown University faculty and students, observed a particle interaction that could be interpreted as a signal from WIMPs, a dark matter candidate — but researchers ...

For the better part of a century, people have been trying to understand dark matter. This invisible substance makes up roughly 85% of the mass in the universe but has never been directly detected.
