QSEA: Quantum Self‐Supervised Learning with Entanglement Augmentation

Lingxiao Li, XiaoHui Ni, Jing Li +2 more

ABSTRACT As an unsupervised feature representation paradigm, Self‐Supervised Learning (SSL) uses the intrinsic structure of data to extract meaningful features without relying on manual annotation. Despite the success of SSL, there are still problems, such as limited model capacity or insufficient representation ability. Quantum SSL has become a promising alternative because it can exploit quantum states to enhance expression ability and learning efficiency. This letter proposes a Quantum SSL with entanglement augmentation method (QSEA). Different from existing Quantum SSLs, QSEA introduces an entanglement‐based sample generation scheme and a fidelity‐driven quantum loss function. Specifically, QSEA constructs augmented samples by entangling an auxiliary qubit with the raw state and applying parameterized unitary transformations. The loss function is defined using quantum fidelity, quantifying similarity between quantum representations and effectively capturing sample relations. Experimental results show that QSEA outperforms existing quantum self‐supervised methods on multiple benchmarks and shows stronger stability in decorrelation noise environments. This framework lays the theoretical and practical foundation for quantum learning systems and advances the development of quantum machine learning in SSL.

Self-supervision with quantum classifiers

Minh-Hieu Tran, Nam-Hai Nguyen, Phuong-Nam Nguyen +1 more

Self-supervised learning (SSL) has emerged as a novel method for learning representations from inputs without data annotations. A key challenge in SSL is avoiding the collapse of representations, leading to poor predictive models. This research proposes an SSL framework that leverages quantum classifiers to address this issue. We achieve well-stratified, nontrivial representations by embedding data into the Hilbert space via quantum classifiers. The algorithm works by minimizing the Kullback-Leibler (KL) divergence to maximize the agreement of positive pairs and minimize the agreement of negative pairs. We demonstrate the proof-of-concept in image classification tasks using MNIST, KMNIST, and FashionMNIST datasets. Classifiers trained with our framework achieve higher predictive performance than classical classifiers, with a maximum accuracy of 65% on MNIST and more than 70% on KMNIST and FashionMNIST using unseen samples without fine-tuning. The code implementation is available at https://github.com/namhai03/QSSL

AutoQML: A Framework for Automated Quantum Machine Learning

Marco Roth, David A. Kreplin, Daniel Basilewitsch +8 more

Automated Machine Learning (AutoML) has significantly advanced the efficiency of ML-focused software development by automating hyperparameter optimization and pipeline construction, reducing the need for manual intervention. Quantum Machine Learning (QML) offers the potential to surpass classical machine learning (ML) capabilities by utilizing quantum computing. However, the complexity of QML presents substantial entry barriers. We introduce AutoQML, a novel framework that adapts the AutoML approach to QML, providing a modular and unified programming interface to facilitate the development of QML pipelines. AutoQML leverages the QML library sQUlearn to support a variety of QML algorithms. The framework is capable of constructing end-to-end pipelines for supervised learning tasks, ensuring accessibility and efficacy. We evaluate AutoQML across four industrial use cases, demonstrating its ability to generate high-performing QML pipelines that are competitive with both classical ML models and manually crafted quantum solutions.
