摘要

Quantum decoherence?in all its locus of essence, and expression is the loss of?coherence?or ordering of the?phase angles?between the components of a system in a?quantum superposition. Detrimental ramifications, and pernicious implications of this dephasing?leads to classical or probabilistically additive behavior. Quantum decoherence gives the?appearance?of?wave function collapse?(the reduction of the physical possibilities into a single possibility as seen by an observer. Here it is to be noted that perception is not the reality and what you see is not what you see ;what you do not see is what you do not see; what you see is what you do not see ;and what you do not see is what you see.)… Thus in all its wide ranging manifestations, it justifies the propositional subsistence and corporeal reality that justifies the framework and intuition of?classical physics?as an acceptable approximation: decoherence is the mechanism by which the?classical limit?emerges out of a perceptual field of quantum starting point and it determines the location of the quantum-classical boundary. Decoherence occurs when a system interacts with its environment in a?thermodynamically irreversible?way. This prevents transitive states, substantive sub states and determinate orientation different elements in the?quantum superposition?of the system and environment's?wavefunction?from?interfering?with each other. Decoherence has been a subject of active research since the 1980s. Decoherence?can be viewed as the principal frontier of diurnal dynamics that results in loss of information from a system into the environment (often modeled as a?heat bath),?since every system is loosely coupled with the energetic state of its surroundings, with particularistic predicational pronouncements. . Viewed in isolation, the system's dynamics are non-unitary?(although the combined system plus environment evolves in a unitary fashion).?Thus, the dynamics of the system aphorism and anecdote of the system alone are?irreversible. As with any coupling,?entanglements?are generated in its theme and potentialities between the system and environment, which have the effect of sharing quantum information with—or transferring it to—the surroundings. It is a blatant and flagrant misconception that collapse of wave function is attributable and ascribable to wave function collapse; Decoherence does not generate?actual?wave function collapse. It only provides an explanation for the?appearance?of the wavefunction collapse, as the quantum nature of the system "leaks" into the environment. So, the wave function collapse is the figment of the observer’s imagination, product of puerile prognostication and resultant orientationality of his phantasmagoria. One cannot have the apodictic knowledge of reality that is; components of the wavefunction are decoupled from a coherent system, and acquire phases from their immediate surroundings. A total superposition of the global or?universal wavefunction?still exists (and remains coherent at the global level), but its ultimate fate remains an?interpretational issue. This is a very important pharisaical provenience and plagenetious precocity with all the disembodied resemblances of the system in total form; specifically, decoherence does not attempt to explain the?measurement problem. Rather, decoherence provides an explanation for the transition of the system to a mixture of states that seem to correspond to those states observers perceive. Moreover, our observation tells us that this mixture looks like a proper?quantum ensemble?in a measurement situation, as we observe that measurements lead to the "realization" of precisely one state in the "ensemble".Decoherence represents a challenge for the practical realization of?quantum computers, since they are expected to rely heavily on the undisturbed evolution of quantum coherences. Simply put; they require that coherent states be preserved and that decoherence is managed, in order to actually perform quantum computation. In the following we give a model for decoherence of the environment, coupled quantum states, at determinate and differential levels ,internal resonance in coupled spin systems, and the conflict in the Quantum state operations and decoupling.
