The Earth has a liquid outer and solid inner core. It is predominantly composed of
Fe, alloyed with small amounts of light elements, such as S, O and Si. The detailed
chemical and thermal structure of the core is poorly constrained, and it is di -
cult to perform experiments to establish the properties of core-forming phases at
the pressures (ca. 300 GPa) and temperatures (ca. 5000{6000 K) to be found in the
core. Here we present some major advances that have been made in using quantum
