Introduction
Hybrid quantum-classical techniques are paving the way to address the complexities of quantum chemistry. Researchers are exploring new landscapes by linking constrained optimization with generalized eigenvalue problems through the innovative Unitary Coupled Cluster (UCC) excitation generators. This fresh perspective derives inspiration from the generator coordinate method, allowing researchers to build a robust many-body basis.
Rather than conventional variational quantum eigensolvers, the approach utilizes UCC excitation generators to create an effective Hamiltonian that alleviates common challenges faced by heuristic numerical optimizers. In particular, it avoids the pitfalls of barren plateaus.
What’s unique about this strategy is its adaptability. By developing a hierarchical ADAPT quantum-classical scheme, it achieves a delicate balance between expanding the subspace and optimizing the ansatz. This method is poised to enhance the exploration of complex quantum chemical systems, making simulations more efficient and less resource-intensive.
The pursuit of accurately determining ground and excited state energies remains paramount, as it reveals vital insights into various phenomena, including material properties and catalytic processes. Traditional methods struggle with intricate cases, particularly when strong electron correlations come into play. Through this improved methodology, researchers aim to combine high accuracy with practical computational scalability, bringing us closer to advanced quantum simulations that could redefine our understanding of quantum chemistry.
