Lanczos recursion on a quantum computer for the Green's function and ground state
Thomas E. Baker
A state-preserving quantum counting algorithm is used to obtain coefficients of a Lanczos recursion from a single ground state wavefunction on the quantum computer. This is used to…

Density functionals and Kohn-Sham potentials with minimal wavefunction preparations on a quantum computer
Thomas E. Baker, David Poulin
One of the potential applications of a quantum computer is solving quantum chemical systems. It is known that one of the fastest ways to obtain somewhat accurate solutions classica…
