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

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 ...

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

Scientists developed a two-photon-enhanced metasurface that cuts photon requirements for nanoscale displacement measurement ...

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 ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

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 ...

Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...
