A Quantum Dynamics Tutorial: Visualising Dynamical Decoupling Sequences on the Bloch Sphere
Charlie J. Patrickson, Isaac Bailey, Antonio Orazzo +2
Dynamical decoupling protocols provide a versatile toolbox for robust control of quantum systems, suppressing noise that would otherwise limit their performance. This tutorial aims…
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…
Self-Configuring Quantum Networks with Superposition of Trajectories
Albie Chan, Zheng Shi, Jorge Miguel-Ramiro +3
Quantum networks are a backbone of future quantum technologies thanks to their role in communication and scalable quantum computing. However, their performance is challenged by noi…
