Classifying Complexity with the ZX-Calculus: Jones Polynomials and Potts Partition Functions.

2021 · arXiv (Cornell University)

The ZX-calculus is a graphical language which allows for reasoning about suitably represented tensor networks - namely ZX-diagrams - in terms of rewrite rules. Here, we focus on problems which amount to exactly computing a …
