Quantum boomerang effect of light.
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
The quantum boomerang effect is a counterintuitive phenomenon in which a wave packet launched with finite momentum in a disordered medium returns to its origin. However, up to now, the experimental exploration of this boomerang effect remains largely unexplored. Here, we report the observation of this effect with light in an on-chip, one-dimensional (1D) disordered waveguide lattice. After benchmarking the system through Anderson localization, we launch a kinetic light beam into the system and track its center of mass (COM): it first moves away from its starting point, arrives at a maximum-valued point, reverses its direction, and returns to its original position over time, revealing the real-space observation of the photonic quantum boomerang effect. We also show two methods to accelerate and control the return: a symmetric gradient loss and time-varying coupling control to effectively increase the return velocity. Both strategies are realized experimentally and captured by our model. These results establish a controllable photonic platform for boomerang physics and open an avenue for future study in nonlinear and many-photon regimes.
