  简介:

An important progress in the field of measurement-based quantum computation (MBQC) in the past decade is the discovery of one-dimensional (1D) symmetry protected topological states as MBQC resource states. In a recent work [arXiv:2210.05089] by Robert Raussendorf et. al., a deep connection between string order parameters in condensed matter physics and a computational order parameter for MBQC is found, where the computational order parameter can be used to quantitatively characterize the computational power of a many-body spin-1/2 system. In this talk, I will discuss the generalization of the framework to qudit systems, and show that the computational order parameter exactly matches with the conventional string order parameter.
