A Divide-and-Conquer Quantum-Selected Configuration Interaction for Evaluating $\pi$-$\pi$ Stacking Interaction Energies in the Benzene Dimer

Accurate evaluation of $\pi$--$\pi$ stacking interactions requires a description of electron correlation on a small energy scale. Direct variational quantum calculations of the benzene dimer with CAS(28e,20o) require 40 qubits and deep circuits. Here, we propose Divide-and-Conquer Quantum-Selected Configuration Interac...
