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…

An Error-aware and Adaptive Method for the Estimation of Quantum Observables on Qudit-Based Quantum Computers

Rick P. A. Simon, Michael Meth, Francesco Martini +4

The accurate estimation of observables is a crucial task in quantum computing. Recent advances have highlighted the need for (a) specialized protocols for qudit-based devices, that…

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…

Correlations enable lossless ergotropy transport

Rick P. A. Simon, Janet Anders, Karen V. Hovhannisyan

"A battery powers a device" can be read as "work stored in the battery is being transported to the device." In quantum batteries, the total amount of stored work can be measured by…
