Gapped Parent Hamiltonians for the Strongly Deformed Toric Code
Nandagopal Manoj, Zack Weinstein, Jason Alicea
Local non-unitary deformations of topologically ordered wavefunctions can drive transitions into peculiar states that challenge modern perspectives on gapped quantum matter. The st…
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.…
Experimental observation of conformal field theory spectra
Xiangkai Sun, Yuan Le, Stephen Naus +6
Conformal field theories (CFTs) feature prominently in high-energy physics, statistical mechanics, and condensed matter. For example, CFTs govern emergent universal properties of s…
Probing Defects with Quantum Simulator Snapshots
Abhijat Sarma, Nayan Myerson-Jain, Yue Liu +4
Snapshots, i.e. projective measurements of local degrees of freedom, are the most standard data taken in experiments on quantum simulators. Snapshots are usually used to probe loca…
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…
