    • ...The emergence of classical dynamics at a macroscopic scale was derived mathematically from quantum dynamics [12], and also less formally from decoherence [13] Consistent histories clarified the language and logic of quantum mechanics [14‐17], and removed many paradoxes [18]...
    • ...This difficulty is sometimes circumvented by taking the whole universe outside A + m as the environment and assuming a pure state of the universe [13, 27], but this way out has drawbacks, not even mentioning that it extends the axioms of quantum mechanics far wider than their established domain and precisely to bypass their limitations...
    • ...There is no end to this growth and some authors assume even that this entanglement can extend to the whole universe, leading finally to some version of Everett’s interpretation [13, 27]...
    • ...In spite of the wealth of its results and its perspectives [13, 31], decoherence theory remains often limited by an insistence on the role of pointers and of the reduced density matrix...

    • ...[21], 3.3.1, p.110): continual measurement “freezes” the motion: the rate of decay of a pure state (as a function of t) goes as (� H)2t2, the “space” (squared) travelled by the state under the Schr¨ odinger...

    Mauro Speraet al. On some hydrodynamical aspects of quantum mechanics

    • ...Actually, the biggest enemy of entanglement is decoherence which is believed to be the responsible mechanism for emergence of the classical behavior in quantum systems [5,6]...

    • ...This interpretation of Planck’s quanta as nodes of a wave function has recently been directly confirmed in an elegant experiment by determining the Wigner function for n-photon states in a single cavity mode [8] (cf. also Fig. 3.14 of [6])...
    • ...Therefore, he can perform different unitary transformations in the four different branches, all leading to the same intended final spinor or CK state—and this is called quantum teleportation [26] (see also E. Joos on p. 173 of [6])...

    • ...Actually, this process offers a clue to better understand the elusive boundary between the quantum and the classical descriptions [1]...
