Molecular Quantum Circuit Design — •Jakob Kottmann — Institut for Computer Science, University of Augsburg

An integral part of science is the formulation of simple concepts capable to capture the essential aspects of complex processes. A prominent examples is the reduction of molecules to simple graphs with the atomic nuclei as vertices connected by edges representing so - called chemical bonds.

Design principles for the construction of quantum circuits are in high demand and are currently being researched heavily - current methodologies however often lack simplicity and interpretability.

Here, an interpretable design concept for quantum circuits based on chemical graphs is presented. It provides physical insight and interpretaility for each individual circuit element and leads to heuristics for the construction, optimisation, and interpretation of quantum circuits suitable for ground state preparation.
