Summary

• What is new: A quantum-secured single-pixel imaging technique that identifies spoofing attacks and enables true image reconstruction, a significant advancement over previous methods that were limited by a threshold error rate.
• Why this is important: Previous quantum-secured protocols were limited by a threshold error rate and could not effectively ensure the security of images against spoofing attacks, where adversaries send fake signals to deceive the imaging systems.
• What the research proposes: The proposed QS-SPI technique analyzes a specific mode correlation of a photon-pair, which allows for the identification of both the region targeted by the spoofing attack and the type of attack, enabling the reconstruction of the true image.
• Results: The proof-of-principle demonstration showed successful image reconstruction even when subjected to spoofing signals 2000 times stronger than the true signals.
