Attention-based optimizer for symmetry finding
Shreya Banerjee, Vinodh Raj Rajagopal Muthu, Charlie Nation +5
Finding symmetries is crucial for understanding physical models. In this work, we present an optimization framework that searches Pauli symmetries of Hamiltonians, merging the fiel…
Graph automorphisms to obtain Clifford symmetries in open and closed qudit models
Charlie Nation, Rick P. A. Simon, Shreya Banerjee +4
In the recent article [arXiv:2605.18966], we demonstrated that finding Clifford symmetries can be mapped to a Graph Automorphism (GA) problem. Here, we provide an algorithm to obta…
Clifford symmetries in quantum many-body systems
Charlie Nation, Rick P. A. Simon, Shreya Banerjee +4
Obtaining the symmetries of a model is a critical step towards developing an understanding and ultimately analytically or numerically solving the model. However, finding symmetries…
Probing the ergodicity breaking transition via violations of random matrix theoretic predictions for local observables
Venelin P. Pavlov, Peter A. Ivanov, Diego Porras +1
Quantum many-body systems can exhibit distinct regimes where dynamics is either ergodic, dynamically exploring an extensive region of available state-space, or non-ergodic, where t…
Analytical determination of multi-time correlation functions in quantum chaotic systems
Yoana R. Chorbadzhiyska, Peter A. Ivanov, Charlie Nation
The time-dependence of multi-point observable correlation functions are essential quantities in analysis and simulation of quantum dynamics. Open quantum systems approaches utilize…
Enhanced measurements on quantum computers via the simultaneous probing of non-commuting Pauli operators
Rick P. A. Simon, Zheng Shi, Charlie Nation +2
Measuring the state of quantum computers is a highly non-trivial task, with implications for virtually all quantum algorithms. We propose a novel scheme where identical copies of a…
