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 ...

Scientists are learning to sculpt photons into powerful new forms, opening the door to high-capacity quantum technologies.

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Novel quantum gate. A new heralded photonic gate entangles two four-level qudits, using orbital angular momentum instead of ...

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 ...

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 ...

A team of researchers of the University of Stuttgart and Julius-Maximilians-Universität Würzburg led by Stuttgart’s Prof. Stefanie Barz has demonstrated a source of single photons that combines ...
