An Optimal Product-State Approximation for 2-Local Quantum Hamiltonians with Positive Terms

Ojas Parekh, Kevin Thompson

We resolve the approximability of the maximum energy of the Quantum Max Cut (QMC) problem using product states. A classical 0.498-approximation, using a basic semidefinite programm…
