Quantum Federated Learning (QFL) integrates the principles of quantum mechanics with classical machine learning to address the privacy challenges in distributed learning settings. This study introduces a Quantum Enhanced Federated Learning framework with Differential Privacy (QE-FLDP), designed to enhance privacy protections by leveraging quantum mechanics principles. The framework uses a quantum feature engineering circuit that encodes classical data into high-dimensional quantum states through parameterized quantum gates, including Rx rotations and CNOT gates. To ensure privacy, Differential Privacy is incorporated via the Laplace mechanism to safeguard data during the training process. Additionally, the framework integrates Quantum Homomorphic Encryption (QHE), enabling secure computations on encrypted data without exposing the underlying information. Model updates are transmitted over quantum channels post-training, preserving data integrity and ensuring compliance with privacy standards. The QE-FLDP framework was evaluated on synthetic datasets, achieving an average Mean Squared Error (MSE) of 0.0143 and an R2 score of 0.987 over 100 training rounds. These results highlight the potential of quantum principles to improve both model accuracy and data privacy in distributed learning settings.

The utilization of quantum technology in this context serves to strengthen the fundamental principles of cryptography, while simultaneously introducing a novel approach to enhancing privacy. Moreover, the study explores the potential of the framework to accommodate various datasets from different cooperating entities, while also resolving the difficulties presented by the diversity of the data. The framework’s success in accommodating multiple machine learning models and applications is demonstrated by evaluations of scalability and computing efficiency. In essence, the research paper titled" Quantum-Resilient Privacy-Preserving Federated Learning for Enhanced Data Security" represents a significant progression in the field of safeguarding collaborative machine learning. The quantum-resilient paradigm not only increases privacy but also offers a safe foundation for the future of collaborative machine learning. The issue at hand pertains to the growing apprehensions over the safeguarding of data privacy and security within the context of our technologically advanced day.
Machine learning models in online environments are vulnerable to various adversarial attacks, such as those from generative adversarial networks (GANs) attacks and more powerful attacks based on recent advances in quantum computing. Federated Learning (FL), a modern privacy preserving distributed machine learning technique, also faces modern data management concerns related to quantum computing. Limiting adversarial learning through quantum mechanics lends itself as an effective security mechanism. This paper introduces a novel quantumencrypted FL framework that integrates randomly-generated quantum noise into an FL environment to improve security against adversarial learning algorithms. These algorithms can conduct reconstruction attacks, which increase privacy leakage through adversarially generated data. Specifically, GAN attacks are effective at creating data samples that resemble training data. Traditional computing techniques can be improved by appending random noise generated by quantum computers as a quantum verification method. The proposed hybrid-quantum encryption approach can fortify a network against generative reconstruction attacks by adding quantum noise to each participant's training data samples. To evaluate the effectiveness of the proposed quantum encryption techniques for protecting FL against GANs, we encrypt the MNIST dataset with quantum-generated keys and then distribute the data in a privacy-preserving manner.
Quantum federated learning (QFL) enables collaborative training of quantum machine learning (QML) models across distributed quantum devices without raw data exchange. However, QFL remains vulnerable to adversarial attacks, where shared QML model updates can be exploited to undermine information privacy. In the context of noisy intermediate-scale quantum (NISQ) devices, a key question arises: How can inherent quantum noise be leveraged to enforce differential privacy (DP) and protect model information during training and communication? This paper explores a novel DP mechanism that harnesses quantum noise to safeguard quantum models throughout the QFL process. By tuning noise variance through measurement shots and depolarizing channel strength, our approach achieves desired DP levels tailored to NISQ constraints. Simulations demonstrate the framework's effectiveness by examining the relationship between differential privacy budget and noise parameters, as well as the trade-off between security and training accuracy. Additionally, we demonstrate the framework's robustness against an adversarial attack designed to compromise model performance using adversarial examples, with evaluations based on critical metrics such as accuracy on adversarial examples, confidence scores for correct predictions, and attack success rates. The results reveal a tunable trade-off between privacy and robustness, providing an efficient solution for secure QFL on NISQ devices with significant potential for reliable quantum computing applications.
As the digital transformation accelerates across industries, the need for robust data protection mechanisms has never been more critical. Sensitive data, particularly in sectors like healthcare, finance, and government, is constantly at risk of exposure due to increasing cyber threats. Traditional encryption techniques, while effective, often fall short when dealing with large-scale data and complex threats. This paper explores the intersection of privacy-preserving techniques, quantum computing, and artificial intelligence (AI) to enhance data protection. We propose the integration of quantum-enhanced AI frameworks that combine quantum computing's unique capabilities with AI-driven privacy-preserving mechanisms. These systems can not only safeguard sensitive data but also improve the efficiency of encryption and decryption processes. The paper discusses the potential of quantum-enhanced AI in creating more secure, scalable, and transparent data protection strategies, while addressing the challenges of implementing such advanced technologies, including computational complexity and ethical considerations. By leveraging quantum algorithms and AI techniques such as homomorphic encryption and differential privacy, the proposed solution aims to provide a futureproof approach to protecting sensitive information from increasingly sophisticated threats.
Abstract Distributed quantum computing, particularly distributed quantum machine learning, has gained substantial prominence for its capacity to harness the collective power of distributed quantum resources, transcending the limitations of individual quantum nodes. Meanwhile, the critical concern of privacy within distributed computing protocols remains a significant challenge, particularly in standard classical federated learning (FL) scenarios where data of participating clients is susceptible to leakage via gradient inversion attacks by the server. This paper presents innovative quantum protocols with quantum communication designed to address the FL problem, strengthen privacy measures, and optimize communication efficiency. In contrast to previous works that leverage expressive variational quantum circuits or differential privacy techniques, we consider gradient information concealment using quantum states and propose two distinct FL protocols, one based on private inner-product estimation and the other on incremental learning. These protocols offer substantial advancements in privacy preservation with low communication resources, forging a path toward efficient quantum communication-assisted FL protocols and contributing to the development of secure distributed quantum machine learning, thus addressing critical privacy concerns in the quantum computing era.
