Imagine the benefits if the entire internet got a game-changing upgrade to speed and security. This is the promise of the quantum internet—an advanced system that uses single photons to operate.

Over the past decade, quantum computing has grown into a billion-dollar industry. Everyone seems to be investing in it, from tech giants, such as IBM and Google, to the US military. But Ignacio Cirac ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Researchers at the Max Planck Institute for the Science of Light (MPL) have demonstrated exceptionally strong broadband helical dichroism (HD) in the visible spectrum using a novel twisted hollow-core ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Interferometers, which modify the properties of light, are used in fiber-optic communication networks, gas sensing, and optical computing applications. The new interferometer, a cascaded-mode device, ...
