The failure of machine learning models to accurately capture causal relationships is becoming increasingly well understood, leading to an explosion of casually motivated machine learning techniques. In this talk we consider the quantum case: can we learn causal structure in a quantum world? We introduce a quantum causal machine learning framework and also consider the possibility of a quantum enhanced agent that learns via explicitly quantum interventions. The latter model of a quantum agent uses optical probes to learn about the external world in a manner that improves upon the classical analogue.

This paper explores the potential of quantum machine learning to revolutionize causal inference within machine learning models. Traditional machine learning often operates as a "black box," lacking transparency regarding the underlying causal relationships driving predictions. We propose a novel framework leveraging quantum mechanics – specifically quantum entanglement and superposition – to achieve precise causal inference. This framework centers around simulating causal relationships using quantum circuits, validating causal effects through quantum measurements, and mitigating measurement errors with quantum error correction. The core claim is that this approach can overcome the limitations of classical methods and provide a fundamentally more accurate and interpretable understanding of complex systems. We outline the key components of this framework, emphasizing the theoretical foundations and potential challenges, and argue for a significant paradigm shift in how we approach causal discovery and model validation within the field of machine learning. The ultimate goal is to build inherently causal quantum machine learning models that are robust to noise and offer unparalleled predictive power. ---
Abstract Modern machine learning (ML) methods typically fail to adequately capture causal information. Consequently, such models do not handle data distributional shifts, are vulnerable to adversarial examples, and often learn spurious correlations (Schölkopf and von Kügelgen 2022 (arXiv:2204.00607) [cs.AI]). Causal ML, or causal inference, aims to solve these issues by estimating the expected outcome of counterfactual events, using observational and/or interventional data, where causal relationships are typically depicted as directed acyclic graphs. It is an open question as to whether these causal algorithms provide opportunities for quantum enhancement. In this paper we consider a recently developed family of non-parametric, continuous causal estimators and derive quantum algorithms for these tasks. Kernel evaluation and large matrix inversion are critical sub-routines of these classical algorithms, which makes them particularly amenable to a quantum treatment. Unlike other quantum ML algorithms, closed form solutions for the estimators exist, negating the need for gradient evaluation and variational learning. We describe several new hybrid quantum–classical algorithms and show that uniform consistency of the estimators is retained. Furthermore, if one is satisfied with a quantum state output that is proportional to the true causal estimand, then these algorithms inherit the exponential complexity advantages given by quantum linear system solvers.

Quantum information technologies, on the one hand, and intelligent learning systems, on the other, are both emergent technologies that are likely to have a transformative impact on our society in the future. The respective underlying fields of basic research-quantum information versus machine learning (ML) and artificial intelligence (AI)-have their own specific questions and challenges, which have hitherto been investigated largely independently. However, in a growing body of recent work, researchers have been probing the question of the extent to which these fields can indeed learn and benefit from each other. Quantum ML explores the interaction between quantum computing and ML, investigating how results and techniques from one field can be used to solve the problems of the other. Recently we have witnessed significant breakthroughs in both directions of influence. For instance, quantum computing is finding a vital application in providing speed-ups for ML problems, critical in our 'big data' world. Conversely, ML already permeates many cutting-edge technologies and may become instrumental in advanced quantum technologies. Aside from quantum speed-up in data analysis, or classical ML optimization used in quantum experiments, quantum enhancements have also been (theoretically) demonstrated for interactive learning tasks, highlighting the potential of quantum-enhanced learning agents. Finally, works exploring the use of AI for the very design of quantum experiments and for performing parts of genuine research autonomously, have reported their first successes. Beyond the topics of mutual enhancement-exploring what ML/AI can do for quantum physics and vice versa-researchers have also broached the fundamental issue of quantum generalizations of learning and AI concepts. This deals with questions of the very meaning of learning and intelligence in a world that is fully described by quantum mechanics. In this review, we describe the main ideas, recent developments and progress in a broad spectrum of research investigating ML and AI in the quantum domain.

This paper explores the potential of quantum machine learning to enhance the generalization and robustness of machine learning models through the application of dynamic topological structure learning. We investigate how quantum algorithms can be utilized to implicitly learn and exploit the inherent topology of quantum systems, offering a novel approach to model representation and learning. The core claim is that this method, by leveraging quantum mechanics, can significantly improve model performance compared to traditional machine learning techniques. This work introduces a framework that dynamically generates and manipulates topological structures, facilitating a more robust and adaptable learning process. The research presents a conceptual framework for quantum-enhanced topological learning and highlights the potential benefits in areas requiring high-dimensional data and complex relationships. The paper details the mechanism, explores preliminary results, and concludes with future directions and implications of this approach.
