Practical attacks on decoy-state quantum-key-distribution systems with detector efficiency mismatch

2015 · Physical Review A

To the active-basis-choice decoy-state quantum-key-distribution systems with detector efficiency mismatch, we present a modified attack strategy, which is based on the faked states attack, with quantum nondemolition measurement ability to restress the threat of detector …

Real-Time Source-Independent Quantum Random Number Generator Based on a Cloud Superconducting Quantum Computer

2021 · Research Square

Abstract Quantum random number generator (QRNG) relies on the intrinsic randomness of quantum mechanics to produce true random numbers which are important in information processing tasks. Due to the presence of the superposition state, quantum …

NCL: Textual Backdoor Defense Using Noise-Augmented Contrastive Learning

2023

At present, backdoor attacks attract attention as they do great harm to deep learning models. By poisoning the training data, the adversary makes the model trained based on this dataset being injected with a backdoor. …
