If one were to think of this pulse as discrete quanta of photon particles, it’d seem to break causality, but as a wave function within quantum physics this is perfectly acceptable. Observations ...

Tapping into quantum science, the scientists combined a photon-firing scanning laser with a new AI model trained to tell the difference between different surfaces imaged with the lasers.

Quantum information can be carried in particles of light called photons. Single photon emitters that emit ... the interplay between light and matter is critical for quantum information processing.
