1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Quantum dots have set benchmarks that far surpass other quantum emitters owing to their ability to deliver high-quality, high-rate and pure photons. However, achieving these exceptional capabilities at telecom wavelengths, bridging the gap to fibre-optic infrastructure and scalable silicon photonics, remains a challenge. Overcoming this difficulty demands high-quality quantum materials and devices that, despite extensive efforts, have not yet been realized. Here we demonstrate waveguide-integrated InAs quantum dots and realize a fully quantum-coherent photon-emitter interface operating in the original telecommunication band (or O-band, 1,260-1,360 nm). We record transform-limited linewidths only 8% broader than the inverse lifetime and bright 41.7-MHz emission rate under 80-MHz π-pulse excitation. These findings showcase the potential of quantum dots for scalable quantum networks.
