Researchers Krishnajith C Vinod and N C Randeep introduced a machine-learning-based quantum teleportation protocol that surpasses traditional Bell-state methods in noisy environments, addressing a key limitation in quantum communication networks. The adaptive protocol optimizes multiple teleportation components, achieving higher fidelity under bit-flip, amplitude damping, and depolarizing noise—both in single-qubit and two-qubit channels—demonstrating broad applicability. Experiments showed substantial fidelity improvements over conventional Bell teleportation, particularly in specific noise conditions, offering a practical solution for real-world quantum networks plagued by decoherence. The AI-driven approach uncovered nontrivial strategies for compensating information loss, revealing new insights into decoherence mitigation without manual algorithm design. This work highlights the potential of automated systems to discover optimal quantum algorithms, paving the way for more resilient and adaptive quantum communication frameworks.

Unfortunately, the interaction with external and internal noise severely affects the quality of teleportation and poses limitations on practical applications of quantum communication networks. In this work, instead of conventional Bell teleportation, we introduce a Machine Learned adaptive protocol for optimizing multiple components of Quantum Teleportation in order to achieve higher fidelity in various noise environments. In order to demonstrate the performance of the proposed scheme, we study three different noise models, including bit-flip, amplitude damping, and depolarizing noise, both in case of single-qubit and two-qubit channels. As a result, we observe substantial improvement in the teleportation fidelity in comparison to the classical Bell-state teleportation protocol in certain noise conditions. Furthermore, the machine-learned protocol reveals a nontrivial strategy for compensation of decoherence and information losses. In addition, obtained results indicate the flexibility and reliability of the proposed framework for implementing various adaptive quantum communications while shedding light on possibilities of discovery of optimal quantum algorithms by means of automated approache Comments: Subjects: Quantum Physics (quant-ph) Cite as: arXiv:2605.16467 [quant-ph] (or arXiv:2605.16467v1 [quant-ph] for this version) https://doi.org/10.48550/arXiv.2605.16467 Focus to learn more arXiv-issued DOI via DataCite (pending registration) Submission history From: N C Randeep [view email] [v1] Fri, 15 May 2026 11:02:39 UTC (465 KB) Full-text links: Access Paper: View a PDF of the paper titled Beyond Bell Teleportation: Machine-Learned Adaptive Protocols, by Krishnajith C Vinod and 1 other authorsView PDFHTML (experimental)TeX Source view license Current browse context: quant-ph new | recent | 2026-05 References & Citations INSPIRE HEP NASA ADSGoogle Scholar Semantic Scholar export BibTeX citation Loading...
