We break down the analysis for the particular case of the Glycine-Glycine dipeptide (top left dipeptide in Figure ) in Figures and. Figure index. The I paq AB between the nitrogen and carbon atom in the peptide bond is plotted in Figure as the distance between the atoms is increased while maintaining the geometries of the individual amino acids (see Figure ). The computed AMI between the atoms forming the peptide bond in Gly-Gly was 3.52 nat at an equilibrium distance of 1.36 Å. As the bond length increases, the I paq AB between the nitrogen and carbon atoms in the peptide bond decreases, reflecting weakened electronic correlation between these two atoms (see blue circles in Figure ). However, the rate of this reduction slowed down at 2.4 Å where the total energy of the system, shown in Figure , indicates the presence of a transition into a dissociated state of two unsaturated radicals. Interestingly, when the peptide bond is indeed saturated with a water molecule (see Figure ) the rate of I paq AB reduction increases significantly around 2.0 Å, indicating the onset of rapid electronic destabilization. Beyond 2.4 Å, as the bond length stretches further, the separated saturated amino acids exhibit weak van der Waals interactions, which are reflected in small but non-zero I paq AB values ranging between 10 ´1 nat and 10 ´5 nat. From this Figure, the correlation between I paq AB and interatomic distance is clear, which can be understood from a chemical point of view. At the top left corner of each of the twelve figures, we find the atom pairs at short interatomic (bond) distances with high I paq AB , which are easily identified as the covalently bonded atom pairs. At larger distances, we find atom pairs that interact predominantly via non-covalent interactions, which are characterized by a decreased level of correlation. More importantly, we observe a consistent linear correlation in the semi-log plot, pointing towards an exponential decay of I paq AB or quantum correlations as a function of distance, underscoring the nearsightedness or locality of interatomic interactions. The R 2 linear regression score provides a measure of the validity of the exponential decay, which is around R 2 " 0.80 for all presented systems, providing a reasonable confirmation of the exponential decay relation.
