Abrams and Lloyd use quantum phase estimation to find energy levels

Jul 24, 1998

Daniel Abrams and Seth Lloyd describe an efficient quantum method for finding a system's energy levels and preparing the corresponding states. It requires efficiently simulated dynamics and an initial guess with sufficient overlap with the desired state.

Why it matters

This connects quantum phase estimation to physics and chemistry calculations, while making the quality of the starting state a crucial condition for the speedup.
