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 light sources with configurable photon lifetimes are essential for large-scale quantum circuits, enabling applications in programmable quantum computing, quantum communications, and quantum metrology. However, the fundamental trade-off between efficiency and photon lifetime imposes significant challenges on the design of high-performance, large configurable lifetime quantum light sources. Here, we report on such chip-scale quantum light sources by harnessing the unique feature of parity-time (PT) symmetry. The core design centers on employing PT-symmetric coupling between two microresonators of distinct circumferences, enabling a broad range and selective tuning of the intracavity photon density of states. By controlling the alignment between resonators, we achieved a near 20-fold photon lifetime tuning range (7.1 ± 1.5 ~ 129.6 ± 1.9 ps), with the shortest lifetimes near the exceptional point (EP). The device generates energy-time entangled photon pairs with 87.1 ± 1.1% interference visibility and a heralded second-order autocorrelation of
