Parameterizing density operators with arbitrary symmetries to gain advantage in quantum state estimation

I Corte, M Losada, D Tielas, F Holik, L Rebón - Physica A: Statistical …, 2023 - Elsevier
In this work, we show how to parameterize a density matrix that has an arbitrary symmetry,
knowing the generators of the Lie algebra (if the symmetry group is a connected Lie group) …

Group-invariant estimation of symmetric states generated by noisy quantum computers

F Holik, M Losada, G Zerr, L Rebón, D Tielas - arXiv preprint arXiv …, 2024 - arxiv.org
The problem of quantum state estimation is crucial in the development of quantum
technologies. In particular, the use of symmetric quantum states is useful in many relevant …
