@ericyocam6Can Hybrid Quantum Neural Networks Improve Adversarial AI Security?
Neural networks can achieve impressive classification accuracy, yet carefully crafted adversarial examples can cause them to make incorrect predictions.
In one of my research POCs, I explored whether a hybrid architecture combining classical deep learning and simulated quantum circuits could be trained to resist compounded adversarial attacks.
The framework integrates a Convolutional Neural Network (CNN) with a Quantum Neural Network (QNN) using Google's Cirq library.
Some interesting experimental findings:
- FGSM + PGD attacks reduced undefended classification accuracy from 98% to 20%.
- Adversarial training restored accuracy to 98% under the tested conditions.
- The framework also evaluates combinations involving Carlini-Wagner, BIM, and DeepFool attacks.
- Quantum circuit components incorporate parameterized rotations and CNOT entanglement gates.
The experiments demonstrate improvements from adversarial training, although they do not establish that the quantum component independently provides greater robustness than classical alternatives.
My question for the Lounge.ai community:
As quantum machine learning develops, could hybrid classical-quantum architectures offer new approaches to securing AI models, or will improvements primarily come from better classical adversarial training techniques?
Interested in hearing perspectives from AI security researchers, quantum developers, and machine learning engineers.

A drop from 98% right to 20% under attack is something a company could watch happen to its own system in an afternoon. I'd offer a few ID verification or document scanning companies a free test of their image checks against these same attacks, because a before and after on their own system would show you quickly who will pay for the fix, quantum or not.
Great suggestion, Ryan! Testing against real-world applications would be a valuable next step, particularly in areas like identity verification and document processing, where adversarial manipulation could have significant consequences. The challenge would be moving from controlled research experiments to evaluating production systems under realistic attack conditions, with appropriate authorization and safeguards.
I also agree that demonstrating measurable improvements in robustness would be more compelling to businesses than the underlying architecture alone. Whether the solution is classical, quantum, or hybrid, the real value comes from improving security without significantly compromising accuracy, performance, or operating costs. Appreciate the practical business perspective!
