Recently, the experimental realization of a quantum computer has been the focus of extensive research. One of the main problems of the physical implementation of well known quantum algorithms is the creation and manipulation of entanglement between qubits. Any physical system is subject to interaction with the environment, which inevitably leads to decoherence and dissipation. One way to compensate for this destructive environmental influence in the unitary imple- mentations of the quantum algorithms is to introduce error-correcting codes. However, this approach treats the interaction with the environment as an effect the influence of which needs to be minimized.

A paradigm shift in looking for alternative strategies to realize quantum computers was induced with the theoretical prediction that dissipation can be used to create complex entangled states and to perform universal quantum computation. This fundamental change is based on the assumption that one can manipulate the coupling of a system to an environment in such a way that the system is driven towards a thermal state, which is the solution of a particular quantum computing task or a target state in quantum state engineering. The feasibility of this strategy was demonstrated by implementing dissipative quantum state engineering with ensembles of atoms and trapped ions.
