摘要: Dephasing and decay are the intrinsic dissipative processes prevalent in any open quantum system dominant mechanisms for loss of coherence entanglement. This inadvertent effect not only can be overcome but even capitalized on a simulation by means tailored couplings between environment. In this context it has been demonstrated that universal computation performed using purely elements, furthermore, efficient preparation highly entangled states is possible. article, we interested nonequilibrium phase transitions appearing systems exploration phases terms simulation. To elucidate these concepts, scrutinize exemplarily two paradigmatic models: transverse-field Ising model considerably more complex ${\mathbb{Z}}_{2}$ lattice gauge theory. We show diagrams parallel Hamiltonian ``blueprint'' theories.
