On dissipative two-state quantum cells and cellular networks

摘要

Quantum cellular networks are structures composed of two-state quantum cells in equilibrium with a stationary thermal bath, which interact among themselves in a classical way. It is shown that if system-bath coupling is set up in the representation based on the given states, as done in the literature, or in the energy representation, as the theory assumes under several approximations, different models are obtained for the cell performance, and hence for the dynamics of the whole network. The model based on the state representation could also be derived by a heuristic approach. The final choice should be decided by experiment.
