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

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

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

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 ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...

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

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 ...
