Photons weaken in optical fibers, and unlike classical light, quantum information cannot be copied or amplified. Quantum ...

Photonic quantum processors, devices that can process information leveraging quantum mechanical effects and particles of ...

A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, ...

Researchers at the University of Stuttgart have successfully teleported quantum states between photons from two distant light sources, marking a pivotal advance toward practical quantum repeaters.

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic ...

Those of us who grew up watching Luke and Leia on screen have probably wondered at one point or another why we don’t have lightsabers. The basic reason why is because the photons that make up light do ...

Researchers from the University of Twente, in the Netherlands, say that they have gained “important insights” into photons, which “behave in an amazingly greater variety than electrons surrounding ...

In the past century, technology was transformed by the first quantum revolution, where utilization of some aspects of quantum mechanics—such as energy quantization or wave–particle duality—enabled ...
