The exact solution of Schrodinger equation for atoms, molecules and extended systems continues to be a "Holy Grail" problem that the entire field has been striving to solve since its inception. Recently, breakthroughs have been made in the development of quantum annealing and coherent Ising machines capable of simulating hundreds of connected spins interacting with an Ising type Hamiltonian. One of the most vital questions pertaining to these new devices is: "can these machine be used to perform electronic structure calculations?" Here we  show that there is an exact mapping between the electronic structure Hamiltonian  and the Ising Hamiltonian.
