Quantum decoder at Rail Vision (Nasdaq: RVSN) subsidiary unit team

Rhea-AI Filing Summary

Rail Vision Ltd. reports that its majority-owned subsidiary, Quantum Transportation, has developed and validated a first-generation transformer-based neural decoder aimed at universal quantum error correction. In simulations across multiple quantum error correction codes and realistic noise environments, the decoder delivered higher decoding accuracy and efficiency than leading classical algorithms such as Minimum-Weight Perfect Matching and Union-Find.

The technology uses advanced transformer architectures and a proprietary design to generalize across different code distances, error rates, and noise profiles, supported by a dedicated intellectual property strategy. Rail Vision and Quantum Transportation are collaborating to explore, on a long-term basis, how similar data analysis and computing methods could eventually complement Rail Vision’s AI-driven railway safety systems. Management views this as strengthening the strategic optionality of its investment in Quantum Transportation.

Rail Vision: Quantum Transportation Delivers First Transformer-Based Neural Decoder for Universal Quantum Error Correction

Achieves superior decoding accuracy and dramatically improved efficiency compared to leading classical algorithms

Ra’anana, Israel, Jan. 15, 2026 (GLOBE NEWSWIRE) - Rail Vision Ltd. (Nasdaq: RVSN) (“Rail Vision” or the “Company”), an early commercialization stage technology company seeking to revolutionize railway safety and the data-related market, announced today that its majority owned subsidiary Quantum Transportation Ltd. (“Quantum Transportation”), a quantum computing innovator, has achieved a major technical breakthrough with the successful prototype development and rigorous validation of its first-generation transformer-based neural decoder - a pioneering, code-agnostic solution designed to advance scalable quantum error correction (QEC).

This innovative decoder harnesses advanced transformer architectures to provide a highly generalizable, machine-learning-driven approach capable of outperforming conventional decoding methods. In comprehensive simulations across diverse quantum error correction codes (including surface code variants) and realistic noise environments, the system has demonstrated superior decoding accuracy and efficiency compared to leading classical algorithms, such as Minimum-Weight Perfect Matching (MWPM) and Union-Find.

Highlights of this achievement include:

	●	Design and finalization of a proprietary transformer architecture specifically optimized for the complex, high-dimensional structure of quantum error syndromes
	●	In-depth benchmarking and comparative analysis against the current state-of-the-art in QEC decoding techniques
	●	Strong evidence of generalization across multiple code distances, error rates, and varying noise profiles
	●	Completion of a solid intellectual property strategy, securing a defensible position for this transformative neural QEC paradigm

This breakthrough aims to support the ongoing collaboration between Rail Vision and Quantum Transportation by combining Quantum Transportation’s quantum-AI based intellectual property and innovation with Rail Vision’s advanced vision and railway-safety technologies. While the decoder is currently focused on quantum computing research applications, the companies are exploring, on a long-term basis, potential areas where similar data analysis and computing methodologies could be applicable to Rail Vision’s core technology.

David BenDavid, CEO of Rail Vision said: “We are pleased with the continued progress at Quantum Transportation. We believe that this breakthrough reflects the strength of its research capabilities and reinforces the strategic optionality of our investment as we evaluate future technology pathways.”

About Quantum Transportation

Quantum Transportation proposes to develop a Quantum Error Correction Simulator powered by a patented Transformer-based Universal Decoder (PD). This decoder, leveraging deep learning techniques, generalizes across quantum codes, learns from noise patterns, and delivers a scalable and hardware-agnostic approach to error correction. The patented Deep Quantum Error Correction Transformer (DQECCT) introduces a novel machine-learning decoder that predicts and refines quantum errors using transformer-based architectures, incorporates masking layers derived from parity-check matrices and optimizes a combined loss function over Logical Error Rate (LER), Bit Error Rate (BER), and Noise Estimation Error. This technology aspires to outperform classical decoders (e.g., MWPM) in both accuracy and speed and uniquely handles faulty measurement scenarios. It is adaptable to various codes - including Surface, Color, Bicycle, and Product Codes.
