Illustration of photon-photon scattering in the laboratory. Two green petawatt lasers beams collide at the focus with a third red beam to polarise the quantum vacuum. This allows a fourth blue laser ...

Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly ...
