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.

A new study from the University of Portsmouth has outlined a possible way to improve how we distinguish between two closely spaced light sources, an issue that has long challenged classical imaging ...

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

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand operation with record-high photon quality in the telecommunications C-band – a key step ...

Photon blockade is a quintessential phenomenon in quantum optics, wherein a strongly nonlinear system prevents the absorption of additional photons once a single photon is present, effectively ...

“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 ...

A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons ...
