A Quantum Computational Approach to Multiconfigurational Valence Bond Theory

Example repository for ArXiv:2302.10660

• h4.py: fast example of ring and linear H4 from paper
• h4-slow.py: slow example (does not need extra structures)
• utils.py: providing extra structures for fast example

In a nutshell

• small quantum circuits are generated via graph-based construction (see ArXiv:2207.12421)
• the total wavefunction is prepared a linear combination of the graph circuits
• parameters are optimized via a global optimization procedure
