Dissipative processs to generate entangled state in solid state system

When the target system interacts with the environment with some dissipative process, this process may be engineered to generate and protect the quantum state. Dissipation can be used to engineer some strongly correlated state, and also help one to understand the dynamics of the system and reservoir. Former work has been completed to design the dissipation in many experimental system, for example, ion trap, superconductor and atomic ensembles system. We demonstrate firstly that by utilizing a designed dissipative protocol one can generate a maximum entangled state in Nitrogen-vacancy solid spin system. Meanwhile, the fidelity of target state will stay steady and not change with the generation sequence number increasing.
