🤖 AI Summary
This work proposes a fully data-driven framework for automatically discovering novel physical phenomena and laws from unlabeled, complex quantum data. By integrating interpretable machine learning with symbolic methods, the approach builds a variational autoencoder–based representation learning architecture that combines symbolic regression, classical shadows, and hybrid discrete–continuous modeling to extract physically meaningful representations directly from raw measurement data and generate concise, analytic order parameters. The method successfully uncovers—without prior physical assumptions—the angular order in Rydberg atom arrays, the phase structure of the cluster Ising model, and hidden correlations in fermionic systems. This establishes a general and interpretable paradigm for quantum state discovery and is accompanied by the open-source qdisc toolkit to facilitate community adoption and further research.
📝 Abstract
Interpretable machine learning techniques are becoming essential tools for extracting physical insights from complex quantum data. We build on recent advances in variational autoencoders to demonstrate that such models can learn physically meaningful and interpretable representations from a broad class of unlabeled quantum datasets. From raw measurement data alone, the learned representation reveals rich information about the underlying structure of quantum phase spaces. We further augment the learning pipeline with symbolic methods, enabling the discovery of compact analytical descriptors that serve as order parameters for the distinct regimes emerging in the learned representations. We demonstrate the framework on experimental Rydberg-atom snapshots, classical shadows of the cluster Ising model, and hybrid discrete-continuous fermionic data, revealing previously unreported phenomena such as a corner-ordering pattern in the Rydberg arrays. These results establish a general framework for the automated and interpretable discovery of physical laws from diverse quantum datasets. All methods are available through qdisc, an open-source Python library designed to make these tools accessible to the broader community.
