Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

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 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 ...

Researchers present a novel ion-trap chip integrating photonics for efficient fluorescence photon collection, enhancing ...

Quantum dots - semiconductor nanostructures that can emit single photons on demand - are considered among the most promising sources for photonic quantum computing. However, every quantum dot is ...

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 ...

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 ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...
