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

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

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 ...

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

Research teams from the Universities of Stuttgart and Würzburg have jointly realised a single photon source that generates photons in the ...

Researchers have demonstrated device-independent quantum key distribution (DI-QKD) over 62 miles (100 kilometers) of ...

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 ...

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 ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...
