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

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

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...

Nearly a century after Albert Einstein and Niels Bohr turned a technical disagreement into a philosophical duel, a new generation of experiments has given Bohr the edge in their most famous clash. By ...

Scientists have introduced a groundbreaking form of quantum entanglement known as frequency-domain photon number-path entanglement. This leap in quantum physics involves an innovative tool called a ...

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

The Stuttgart and Würzburg teams, led by Prof. Sven Höfling, are working within the PhotonQ project, a consortium funded by ...

Driving late at night, you come upon a red light and stop the car. You lift your hand wearily to block the red glow streaming through your windshield. Suddenly, both the green and yellow lights come ...
