Quantum Computing Approach to Atomic and Molecular Three-Body Systems

Mohammad Haidar, Hugo D. Nogueira, J. -Ph. Karr

We present high-precision quantum computing simulations of three-body atoms (He, H $^{-}$ ) and molecules (H $_{2}^{+}$ , HD $^{+}$ ), the latter being studied beyond the Born-Oppenheimer approx…
