Scientists have created a new type of light source that can generate extremely bright entangled photon pairs for use in quantum communications networks.
The light source achieves high brightness and entanglement fidelity by combining a photon dot emitter with a quantum resonator. This is the first time these technologies have been combined.
The new light source produces photons that maintain their quantum properties over greater distances before losing coherence. This brings higher-capacity quantum communication closer to reality.
However, further work is still needed to address issues like the toxicity of materials currently used and integrating structures to counteract decoherence.
While a full quantum internet remains far off, successfully combining technologies to create brighter entangled photons is an important step toward developing practical quantum communication systems with stronger signals over longer ranges.
