In this preprint we present our results on the study of the electromagnetic conductivity in dense quark-gluon plasma obtained within lattice simulations with $N_f = 2 + 1$ dynamical quarks. We employ stout improved rooted staggered quarks at the physical
point and the tree-level Symanzik improved gauge action.
The simulations are performed at imaginary baryon chemical potential, and the
Tikhonov regularisation method is used to extract the conductivity from
current-current correlators.
Our results indicate
an increase of QGP electromagnetic conductivity with real baryon density, and this dependence is quite strong.
