    Abstract

    We investigate the use of quantum-jump-based feedback to manipulate the stability of multipartite entangled dark states in an open quantum system. We use quantum trajectory methods to show a general strategy to isolate subspaces of entangled states. In the case of four qubits, we propose a simple feedback control that, although not optimal, is realistic and stabilizes a highly entangled state.
