All-optical diffractive neural networks process broadband light

Diffractive deep neural network is an optical machine learning framework that blends deep learning with optical diffraction and light-matter interaction to engineer diffractive surfaces that collectively perform optical computation ...

Scientists set record for light-matter interaction

An international team of physicists from the Mandelstam Institute for Theoretical Physics at Wits University and the Institut Néel in Grenoble, France, has created a tiny superconducting circuit that mimics the quantum mechanical ...

Controlling photons with a photon

Photons are considered to be ideal information carriers and expected to play important roles in quantum communication and information processing, where quantum mechanics allows for absolutely secure cryptographic key distribution ...

X-ray Rabi oscillations between nuclei observed in coupled cavities

X-rays interact weakly with matter. This is their greatest strength for many applications, but also a fundamental weakness for others. In particular the fields of nonlinear optics and quantum optics, mainstays for both fundamental ...

Interaction between light and sound in nanoscale waveguide

Scientists from Ghent University and imec announce today that they demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these scales – and ...

Two or one splashing? It's different

If two children splash in the sea high water waves will emerge due to constructive superposition. Different observations are made for the microscopic world in an experiment at the University of Bonn, where physicists used ...

Team first to detect exciton in metal

University of Pittsburgh researchers have become the first to detect a fundamental particle of light-matter interaction in metals, the exciton. The team will publish its work online June 1 in Nature Physics.
