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…
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.…
Intrinsic Heralding and Optimal Decoders for Non-Abelian Topological Order
Dian Jing, Pablo Sala, Liang Jiang +1
Topological order (TO) provides a natural platform for storing and manipulating quantum information. However, its stability to noise has only been systematically understood for Abe…
Decoherence and wavefunction deformation of non-Abelian topological order
Pablo Sala, Jason Alicea, Ruben Verresen
The effect of decoherence on topological order (TO) has been most deeply understood for the toric code, the paragon of Abelian TOs. We show that certain non-Abelian TOs can be anal…
Stability and Loop Models from Decohering Non-Abelian Topological Order
Pablo Sala, Ruben Verresen
Decohering topological order (TO) is central to the many-body physics of open quantum matter and decoding transitions. We identify relevant statistical mechanical models for decohe…
Practical roadmap to measurement-altered criticality in Rydberg arrays
Stephen Naus, Yue Liu, Sara Murciano +3
Weak measurements have been predicted to dramatically alter universal properties of quantum critical wavefunctions, though experimental validation remains an open problem. Here we…
