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…
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…
