Projected Cooling Algorithm for Quantum Computation

The projected cooling algorithm is a quantum computing method that constructs the localized ground state of any Hamiltonian with interactions that vanish at large distances. We start with an initial state with support over a compact region of a large volume. We then drive the excited quantum states to disperse and measure the remaining portion of the wave function left behind. These characteristics make the projected cooling algorithm a promising tool for calculations of self-bound systems such as atomic nuclei.
