Realizing non-Abelian topological order on a trapped-ion processor
Nat Tantivasadakarn, Sherman Fairchild Postdoctoral Scholar,

Join us in 201 E. Bridge for the talk presented over zoom. We'll be hosting lunch following the talk on the lawn north of the Bridge Arcade

Abstract: Non-Abelian topological order (TO) is a coveted state of matter that despite extensive efforts has remained elusive. I will present the first unambiguous realization of non-Abelian TO and demonstrate control of its anyons. Using an adaptive circuit, we create the ground state wavefunction of D4 TO on a kagome lattice of 27 qubits using an adaptive circuit on Quantinuum's H2 trapped-ion quantum processor and obtain fidelity per site exceeding 98.4%. Moreover we are able to experimentally confirm the various features that are unique to non-Abelian phases of matter including: 1) a non-square ground state degeneracy of 22, 2) an excited state with a single anyon on a torus, and 3) a non-trivial phase factor upon tracing three non-Abelian anyons in the shape of Borromean rings in spacetime.
