Optical fiber link to make CERN more on time than ever

A new optical fiber link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing precision and supporting experiments like ALPHA in their search for matter–antimatter differences.

Microsoft joins quantum race with breakthrough chip

Tech giant Microsoft unveiled a new computer chip on Wednesday that it says could transform everything from fighting pollution to developing new medicines, joining Google and IBM in arguing that the promise of quantum computing ...

What is quantum coherence?

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument or a conversation taking place five tables down in a crowded cafe might all be incoherent. In general, ...

Light-powered breakthrough enables precision tuning of quantum dots

Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots—making the process faster, more energy-efficient and environmentally sustainable—without ...
