Quantum secure image encryption using hybrid QTRNG and QPRNG.
Article in Scientific reports, 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
Secure image transmission has become critical in the emerging quantum computing landscape. This research introduces a hybrid key quantum encryption approach that combines Quantum True Random Number Generation (QTRNG) and Quantum Pseudo Random Number Generation (QPRNG) to enhance security and efficiency. The proposed Quantum Hybrid Random Number Generator (QHRNG) integrates entanglement-based true randomness with structured pseudo-randomness using Hadamard, controlled rotation and Clifford gates to generate high-entropy encryption keys. The generated Quantum keys are applied to encrypt grayscale images using the Novel Enhanced Quantum Image Representation (NEQR). The encryption process is strengthened by quantum bit-level scrambling and selective Quantum Fourier Transform. The proposed method is implemented on Qiskit’s Aer and Basic simulators and validated on IBM’s torino quantum hardware. Compared to standalone QTRNG and QPRNG methods, QHRNG consistently provides higher randomness and stronger security in noisy and noiseless environments. This work offers a robust and future-ready framework for quantum secure image encryption.
