29. When photons are used to supply the energy to make such devices work, the probabilistic character of the quantum mechanical representation of light-matter interaction limits the notion of molecular switches and molecular logic gates: the outcome is straightforwardly predictable only if a statistically relevant number of excitation events are taken into account. On the other hand by using chemical inputs, the classical thermodynamic model envisages the formation of equilibrium mixtures in solution that prevents complete switching between different chemical species. Therefore a practical molecular-level device would be better based on ensembles of molecules, as already pointed out in ref. [14a].
