In science:

Pointer states are emergent states of a quantum system, the pointer, or the apparatus, because of interaction with the environment.
Comment on "Hidden assumptions in decoherence theory"
These states of the apparatus emerge as stable states as a result of environment induced super-selection.
Comment on "Hidden assumptions in decoherence theory"
In fact, in the above example, if S is assumed to be the apparatus interacting with the rest of the world, that is, an environment W , it can be used to understand the concept of pointer states.
Comment on "Hidden assumptions in decoherence theory"
However, the apparatus of commutator theory, in particular, the existence of a difference term, allows us to prove an important lemma (lemma 3.2) which lets us work with a simpler and more conceptual definition of an extension than that in .

A General Argument Against the Universal Validity of the Superposition Principle
That the measuring apparatus can be prepared in a precise state |M0 i: since the instrument is a macroscopic ob ject with many degrees of freedom, it is impossible to know its precise state at any given time.
A General Argument Against the Universal Validity of the Superposition Principle
That one can safely neglect the interactions between the apparatus and the surrounding environment.
A General Argument Against the Universal Validity of the Superposition Principle
That the final state of the apparatus gets perfectly correlated to the initial state of the microscopic system: this is an highly idealized characteristic which is not shared by any realistic physical instrument.
A General Argument Against the Universal Validity of the Superposition Principle
A measuring apparatus is a macroscopic system which, interacting with the microsystem whose properties one is interested in ascertaining, ends up into a state more or less correlated with the eigenstates of the observable it is devised to measure.
A General Argument Against the Universal Validity of the Superposition Principle
For simplicity, in what follows we will assume that the apparatus has a pointer movable along a scale, whose position registers the result of the measurement.
A General Argument Against the Universal Validity of the Superposition Principle
Contrary to microsystems, the measuring apparatus, being a macroscopic ob ject, has many degrees of freedom, most of which — in particular the microscopic ones — we cannot control at all; and of the macroscopic ones, like the position of the pointer, we can have only a very limited control.
A General Argument Against the Universal Validity of the Superposition Principle
Moreover, the apparatus, due to its dimensions, is always interacting with the environment (whose degrees of freedom are also essentially out of control).
A General Argument Against the Universal Validity of the Superposition Principle
Note that in the above equations (5.1) and (5.2) the index α distinguishes various possible and uncontrollable situations of the measuring apparatus in its “ready” state.
A General Argument Against the Universal Validity of the Superposition Principle
The only thing we require is that the measuring apparatus is reliable to a high degree, i.e. that it can safely be used to measure the state of the microsystem since, in most cases, it gives the correct answer.
