Quantitative prediction of nuclear-spin-diffusion-limited coherence times of molecular quantum bits based on copper(ii)

Abstract

We have investigated the electron spin dynamics in a series of copper(II) β-diketonate complexes both in frozen solutions and doped solids. Double digit microsecond coherence times were found at low temperatures. We report quantitative simulations of the coherence decays solely based on the crystal structure of the doped solids.
