Engineering steady states using jump-based feedback for multipartite entanglement generation

Stevenson, Robin; Hope, Joseph; Carvalho, Andre


We investigate the use of quantum-jump-based feedback to manipulate the stability of multipartite entangled dark states in an open quantum system. Using the model proposed in Phys. Rev. APLRAAN1050-294710.1103/PhysRevA.76.010301 76, 010301(R) (2007) for a pair of atoms, we show a general strategy to produce many-body singlet stationary entangled states for larger number of atoms. In the case of four qubits, we propose a simple local feedback control that, although not optimal, is realistic and...[Show more]
