Quantum Algorithm for Molecular Properties and Geometry Optimization [PDF]

open access: yes, 2009
It is known that quantum computers, if available, would allow an exponential decrease in the computational cost of quantum simulations. We extend this result to show that the computation of molecular properties (energy derivatives) could also be sped up ...
