This paper focuses on density functional theory (DFT), a particularly popular quantum method for both academic and industrial applications. They devised a procedure to assess the precision of DFT methods. They report the results of a community-wide effort that compared 15 solid-state codes, using 40 different potentials or basis set types, to assess the quality of the Perdew-Burke-Ernzerhof equations of state for 71 elemental crystals.
