| contents | Quantum mechanics has revolutionized our understanding of information transmission, leading to the development of quantum communication protocols that promise unprecedented security in data transfer. Quantum teleportation, in particular, has emerged as a cornerstone protocol for quantum communication, operating within the constraints of noisy intermediate-scale quantum (NISQ) devices that characterize current quantum hardware. While significant progress has been made in demonstrating quantum teleportation, maintaining reliable high-fidelity communication in practical, noisy environments remains an unsolved challenge, particularly in addressing real-time interference detection and mitigation.
Here we show that automated interference detection coupled with a strategic reset protocol significantly enhances the reliability of quantum teleportation under realistic noise conditions. Our system incorporates a novel feedback mechanism that continuously monitors quantum state fidelity and triggers resets when interference is detected, improving both the success rate and robustness of the teleportation process. In 20 experimental trials, our approach achieved an interference detection rate of 65\% and required an average of 3.4 resets per successful teleportation, resulting in a maintained fidelity of 0.92, well above classical limits. This reset mechanism reduced the occurrence of failed transmissions by 40\% compared to non-reset trials, demonstrating its essential role in sustaining high fidelity.
These findings establish a practical framework for robust quantum communication in noisy environments, advancing the field toward reliable quantum networks suitable for real-world applications. |
