Rafael Nepomechie (University of Miami) - Quantum state preparation: from Dicke to Bethe states

Title: Quantum state preparation: from Dicke states to Bethe states
Abstract:
The spin-1/2 Heisenberg quantum spin chain is a paradigmatic model of theoretical physics. We consider the problem of preparing exact eigenstates of this model on a quantum computer. We begin by considering the simpler problem of preparing Dicke states, whose solution we then generalize to Bethe states. We use the latter construction in a VQE setup to estimate Bethe roots.
