'Unbreakable' quantum communication closer to reality thanks to new, exceptionally bright photons
Scientists build a new light source for quantum communications by combining existing technologies together to create a stronger and more robust quantum signal.
In research published 24 July in the journal eLight, scientists from Europe, Asia and South America created a new type of quantum signal source using existing technologies that achieves extremely high brightness. Researchers combined the photon dot emitter with a circular Bragg resonator (a reflector used to guide electromagnetic waves) on a piezoelectric actuator (a device that generates electricity when heat or stress is applied). In pursuit of his writing, Peter has interviewed Professor Freeman Dyson, stuck his head inside a fusion reactor and asked awkward questions of several government ministerial departments.
