Fig. 2From: Periodic plane-wave electronic structure calculations on quantum computersTotal energies as a function of distance from aperiodic and periodic plane-wave FCI calculations for the LiH molecule with 1 and 18 correlation optimized virtual orbitals. The top plot shows energy from R=1.3 Ã…Â to R=2.5 Ã…, and the bottom plot shows energy from R=2.5 Ã…Â to R=7.0 Ã…. The periodic calculations used a simple-cubic supercell (L=15.0 Ã…)Back to article page
