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. |
