Molecular Symmetry in VQE: A Dual Approach for Trapped-Ion Simulations of Benzene

Understand

Understanding complex chemical systems -- such as biomolecules, catalysts, and novel materials -- is a central goal of quantum simulations.

• Near-term strategies hinge on the use of variational quantum eigensolver (VQE) algorithms combined with a suitable ansatz.
• However, straightforward application of many chemically-inspired ansatze yields prohibitively deep circuits.
• In this work, we employ several circuit optimization methods tailored for trapped-ion quantum devices to enhance the feasibility of intricate chemical simulations.
