Room-temperature ultrasensitive photon-level detection in the subterahertz frequency regime.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
In recent years, subterahertz (sub-THz) electromagnetic waves have been increasingly applied in next-generation wireless communications, imaging, spectroscopy, and nondestructive sensing. However, high-sensitivity detection of sub-THz waves is a difficult task for conventional electronic and photonic techniques. Here, we report the first successful demonstration of ultrasensitive room-temperature detection of sub-THz waves using a frequency up-conversion technique based on a backward optical parametric process in periodically poled lithium niobate (PPLN) crystals. The detection sensitivity reached 50 attojoules (aJ), outperforming those of cryogenically cooled bolometers and commercial pyroelectric detectors by several orders of magnitude. Furthermore, the frequency can be flexibly tuned by simply rotating the PPLN crystals. This simple, stable, and highly sensitive photonic scheme can potentially realize sub-THz wave detection for future wireless communications (6G/7G), sensing, imaging, and spectroscopic applications.
