The idea of studying nuclear physics directly from the degrees of freedom of the Standard Model, quarks and gluons, has been long sought in the physics community. During the last few decades, the numerical method called lattice QCD has been able to compute the simplest quantities, such as the hadron masses, directly from first principles.

When trying to address multibaryon systems, more sophisticated algorithms and analysis techniques are required in order to obtain the energy levels.

In this talk, I will present the tools used to extract the lowest-lying spectra of two-baryon systems from the lattice, showing the results obtained by the NPLQCD collaboration at a heavier-than-physical pion mass (800 MeV) and some preliminary results at a lower pion mass (450 MeV).
