Climbing the Fusion Tree: Center Ordering and Decoding Hierarchy in Non-Abelian Mixed States
Pablo Sala, Vlad Temkin, Cenke Xu +2
We develop an operational approach to strong-to-weak spontaneous symmetry breaking (sw-SSB) of a non-Abelian symmetry group G. We formulate it as the decoding task of distinguishin…

Statistical Mechanics and Symmetries of Non-Abelian Anyon Proliferation: From Deformation to Decoherence
Avi Vadali, Robijn Vanhove, Ruben Verresen +2
Topological quantum computation relies on braiding non-Abelian anyons, but requires the underlying topological order to survive imperfect state preparation and environmental noise.…

Quantum sensing with critical systems: impact of symmetry, imperfections, and decoherence
Yinan Chen, Sara Murciano, Pablo Sala +1
Entangled many-body states enable high-precision quantum sensing beyond the standard quantum limit. We develop interferometric sensing protocols based on quantum critical wavefunct…
