Illustration of a metasurface generating pairs of photons (shown as spheres). The photon entanglement can be varied by changing the pump beam (shown in red). Illustration by Andrei Komar & Matthew Parry. Subhed: A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions—an important step towards creating miniaturized […]
Developing countries face many challenges in the fight against infectious diseases. One of these is the lack of access to medical diagnostic tools. This is considered a key reason why malaria and tuberculosis are still two of the leading causes of death in sub-Sahara Africa and parts of Asia. In order to address issue of […]
Researchers show the conversion of infrared images to the visible using ultra-thin and transparent semiconductor nanocrystals.
