Abstract

Travelling light The quantum description of light as photons leads to predictions that have no classical counterpart. Coalescence is a striking example: when two identical photons arrive simultaneously at the two sides of a partially reflecting mirror, they always leave the mirror together. Beugnon et al. demonstrate this effect by producing quantum interference between two single photons emitted by two independently trapped atoms. This is a step towards synchronized, independent sources emitting indistinguishable photons. Such sources would be a useful resource for quantum data processing.
