On Counting (Quantum-)Graph Homomorphisms in Finite Fields of Prime Order

J. A. Gregor Lagodzinski, Andreas Göbel, Katrin Casel +1

We study the problem of counting the number of homomorphisms from an input graph $G$ to a fixed (quantum) graph $\bar{H}$ in any finite field of prime order ${\mathbb{Z}}_p$. The sub…
