  A local quantum phenomenon that gives rise to generic for all surface
reactions macroscopic fluctuations is studied. The issue is viewed with respect
to the necessary conditions for a long-term stable evolution of any natural and
artificial system. It is shown that global coupling of the local fluctuations
is necessary for providing a long-term stability of the system. A successful
coupling mechanism is achieved on the grounds of new assumptions about the
Hamiltonian response to certain perturbations. The coupling mechanism acts
towards a global synchronisation, i.e. to a coherent response of the excited
species to any further perturbation. It is proven that the synchronisation is a
scale-free process that has universal properties, e.g. it is insensitive to the
chemical identity of the reacting species and to the particularities of the
surface reaction. Its hallmark is that the global adsorption rate exhibits
permanent temporal variations whose amplitude is independent of the system
size.
  The presence of these fluctuations fundamentally changes the temporal
behavior of the system, namely it becomes pulse-like both on the quantum and
the macro-level. The pulse-like behavior gives rise to a persistent continuous
band at the quantum spectra whose major properties are: (I) it does not
correspond to any real radiation; (ii) its presence is insensitive to the
particularities of the system and the incident radiation; (iii) its shape and
the infrared edge are typical for the -type noise. These properties give rise
to its name: alias -type noise.
