Laser-enhanced quantum sensing boosts sensitivity and dynamic range.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
While magnetometers based on nitrogen-vacancy (NV) centers in diamond have emerged as the most important solid-state quantum sensors, ensembles are typically limited to a few percent optical contrast. Here, we demonstrate a laser threshold magnetometry-based NV system that achieves 100% optical contrast in combination with strong output signals up to 50 mW. By integrating the NV centers into a laser cavity, we show magnetic-field-dependent shifts of the laser threshold, allowing the laser system to be entirely switched off with the NV centers' magnetic resonance. We determine the photon-shot-noise fundamental sensitivity limit to be < 400 fT/
