A never-before-seen image of individual oxygen atoms dissolved in water has been captured. Scientists used an advanced laser technique called femtosecond two-photon absorption laser-induced ...
Researchers in Germany have taken a major step toward a practical quantum internet. A team at the University of Stuttgart has demonstrated the first transfer of quantum information between photons ...
Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Photon upconversion through high harmonic generation, multiphoton absorption, Auger recombination and phonon scattering performs a vital role in energy conversion and renormalization. Excitons, the ...
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 ...
In school board meetings across Maine, state legislatures in Indiana and Ohio, and university campuses in Illinois, a profound transformation is occurring. Political polarization, partly fueled by the ...
