Research reveals how close human vision comes to sensing the smallest possible unit of light. Here’s why that matters for perception.

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

A long-standing bottleneck in photonic quantum technology may finally be easing. Researchers in Germany ...

Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

Photons are indeed massless, but they still travel through our universe. You can picture the fabric of the cosmos as a sort of grid — one that is four-dimensional and incorporates not only the three ...

In a prospective imaging study of 200 adults with lung cancer, photon-counting CT reduced radiation exposure, yielded fewer ...
