Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.

Modern life runs on light. Fiber-optic cables move data across continents, lasers guide surgeries, and photons sit at the ...
