    Abstract

    We show that direct feedback based on quantum-jump detection can be used to generate entangled steady states. We present a strategy that is insensitive to detection inefficiencies and robust against errors in the control Hamiltonian. This feedback procedure is also shown to overcome spontaneous emission effects by stabilizing states with a high degree of entanglement.
