The Hamiltonian formulation of Lattice QCD with staggered fermions in the strong coupling limit
has no sign problem at non-zero baryon density and allows for Quantum Monte Carlo simulations.
We have extended this formalism to two flavors, and after a resummation, there is no sign problem
both for non-zero baryon and isospin chemical potential. We report on recent progress on the
implementation of the Quantum Monte Carlo simulations.
