For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of ...

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

An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon ...

The experimental layout of the sender Alice and the receiver Bob. Alice’s setup contains the excitation and collection setup of the single photon source, and a Sagnac-like polarization modulator for ...

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

Scientists have created a groundbreaking ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold immense promise for future quantum ...
