Classical variational optimization of a PREPARE circuit for quantum phase estimation of quantum chemistry Hamiltonians

We propose a method for constructing PREPARE circuits for quantum phase estimation of a molecular Hamiltonian in quantum chemistry by using variational optimization of quantum circuits solely on classical computers. The PREPARE circuit generates a quantum state which encodes the coefficients of the...
