Variational Quantum Eigensolver Benchmarking of the Su–Schrieffer–Heeger Model: Ansatz-Conditional Bulk-Spectrum Resolution
The Su-Schrieffer-Heeger chain provides a clean benchmark for variational quantum simulation as it breeds topologically non-trivial states, it is analytically transparent & tractable, yet capable enough to expose the central algorithmic question of whether a shallow variational circuit can reproduce physically meaningf...
