Superior probabilistic computing using operationally stable probabilistic-bit constructed by a manganite nanowire.
Article in National science review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Probabilistic computing has emerged as a viable approach to treat optimization problems. To achieve superior computing performance, the key aspect during computation is massive sampling and tuning on the probability states of each probabilistic bit (p-bit), demanding its high stability under extensive operations. Here, we demonstrate a p-bit constructed by a manganite nanowire that shows exceptionally high stability. The p-bit contains an electronic domain that fluctuates between metallic (low-resistance) and insulating (high-resistance) states near its transition temperature. The probability for the two states can be directly controlled by nano-ampere electrical current. Under extensive operations, the standard error of its probability values is <1.3%. Simulations show that our operationally stable p-bit plays a key role in achieving correct inference in a Bayesian network by strongly suppressing the relative error, displaying the potential for superior computing performance. Our p-bit also serves as a high-quality random number generator without extra data-processing, beneficial for cryptographic applications.
