Data set supporting the content of the article "Extracting Many-Body Quantum Resources within One-Body Reduced Density Matrix Functional Theory" by Carlos L. Benavides-Riveros, Tomasz Wasak and Alessio Recati. The research data includes the universal functionals of Quantum Fisher Information matrices for repulsive and attractive interaction strengths as well as the universal functional for the Bose-Einstein condensate in a double-well Bose-Hubbard model.
