A recently proposed formalism[1] mapping strongly correlated finite-bias transport through a single quantum dot to infinitely many equilibrium models is reviewed. We find significant improvements in data quality by
using continuous-time quantum Monte Carlo. A novel approach for the
double analytic continuation required to obtain the non-equilibrium
correlation functions from simulation data is introduced.
