An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...

A photon enters an extraordinarily intense laser field. When it exits, its polarization has rotated, as though empty space ...

A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...
