  In spite of all of its successes, quantum mechanics leaves us with a central
problem: How does Nature create a "foot-bridge" from fragile quanta to the
objective world of everyday experience? Here we identify within quantum
mechanics a fundamental process leading to the perceived objectivity and called
state information broadcasting. This is the trick that Nature uses instead of a
simple cloning. We uncover it basing on minimal assumptions, without referring
to any dynamical details or a concrete model. More specifically, we show how a
crucial for quantum mechanics notion of non-disturbance due to Bohr and a
natural definition of objectivity lead to a canonical structure of a quantum
system-environment state, reflecting objective information records about the
system stored in the environment.
