Stoquastic Hamiltonians are the class of Hamiltonians that can be studied numerically using standard Quantum Monte Carlo methods--these are the Hamiltonians which do not suffer from the sign problem. These Hamiltonians can also be easier to study analytically because of their connection to nonnegative matrices. In the first part of this talk I will review the arsenal of analytic and numerical tools pertaining to stoquastic Hamiltonians. I will then discuss a variational lower bound for the ground state energy of these Hamiltonians.

I start from a quick overview of the popular definitions of the discord and their physical interpretation in terms of various Maxwell's demons. Then I present a case for discord not telling anything about the local distinguishability, but being useful for understanding of by-local gates.
