Dissipative Preparation of Entanglement

Attempts to perform quantum computation and generate entanglement typically rely on isolating the system from the environment and reach the desired state trough controlled unitary dynamics. In contrast an alternative approach was proposed, which exploits dissipation to generate entanglement and realize quantum computation as the steady state of the dissipative dynamics.Whether this alternative approach is an advantage from an experimental perspective can only be answered by considering concrete physical systems and evaluating what the alternative approach amounts to for those systems.
