Il importe toutefois d'estimer la decoherence (transition) entre les differents etats, et les facteurs qui la determinent particulierement dans l'expression et l'action sociopolitiques.
Over time, the quantum system is continuously influenced to a small extent by the external environment, through a process called "decoherence", process that modifies the wave function, therefore collapsing it to a certain degree [1].
The first, a type of single-spin qubit called a Loss-DiVincenzo qubit, has very high control fidelity -- meaning that it is in a clear state, making it ideal for calculations, and has a long decoherence time, so that it will stay in a given state for a relatively long time before losing its signal to the environment.
The origin of the arrow of time is already described in the process of decoherence. Zeh, who has been instrumental in the decoherence program, misses this insight because he denies the reality of temporal presence and therefore overlooks the role of time in the quantum.

The orthodox view in the standard formalism of quantum mechanics is done via entanglement, wavefunction collapse and decoherence [25].
Destroying superpositions is called decoherence, and it's a big problem.
We take [T.sup.-1.sub.d] [approximately equal to] [bar.V]/h as an estimate of the decoherence time and we introduce r as the natural lifetimes of each state.
The transition to classicality requires a decoherence. The decoherence can be obtained through an interaction with an environment.
More recently, Struve functions appeared in particle quantum dynamic studies of spin decoherence and nanotubes electrodynamics, potential theory, and optics.
