Optimization of the Variational Quantum Eigensolver for Quantum Chemistry Applications

  title={Optimization of the Variational Quantum Eigensolver for Quantum Chemistry Applications},
  author={Ruben Keijzer and V. E. Colussi and Boris vSkori'c and Servaas Kokkelmans},
This work studies the variational quantum eigensolver algorithm, which is designed to determine the ground state of a quantum mechanical system by combining classical and quantum hardware. Two methods of reducing the number of required qubit manipulations, prone to induce errors, for the variational quantum eigensolver are studied. First, we formally justify the multiple Z2 symmetry qubit reduction scheme first sketched by Bravyi et al. [arXiv:1701.08213 (2017)]. Second, we show that even in… Expand
