Summary: Entanglement-informed construction of variational quantum circuits

The variational quantum eigensolver is a promising tool for simulating ground states of quantum many-body systems on noisy quantum computers. Its effectiveness relies heavily on the ansatz, which must be both hardware-efficient and problem-specific. In the publication [JUF25], we explore ideas about entanglement-informed ansatz choices that naturally emerge from specific entanglement structures. We investigate three models focusing on entanglement barriers and long-range interactions. We find that including the entanglement structure in the parameterized quantum circuit reduces the resources necessary to achieve a given accuracy.
