Decoherence

Some articles on decoherence, decoherences:

Quantum Decoherence - Measurement
... understood as an aspect of the normal dynamics of quantum mechanics via the decoherence process ... Consequently, decoherence is an important part of the modern alternative to the Copenhagen interpretation, based on consistent histories ... Decoherence shows how a macroscopic system interacting with a lot of microscopic systems (e.g ...
Quantum Decoherence - In Interpretations of Quantum Mechanics
... Before an understanding of decoherence was developed the Copenhagen interpretation of quantum mechanics treated wavefunction collapse as a fundamental, a priori process ... Decoherence provides an explanatory mechanism for the appearance of wavefunction collapse and was first developed by David Bohm in 1952 who applied it to Louis DeBroglie's pilot wave theory, producing Bohmian ... Decoherence was then used by Hugh Everett in 1957 to form the core of his many-worlds interpretation ...
Decoherence-free Subspaces - Background - Further Development
... to both collective dephasing and dissipation showing that decoherence is prevented in such a situation ... However, such models were limited since they dealt with the decoherence processes of dephasing and dissipation solely ... To deal with other types of decoherences, the previous models presented by Palma, Suominen, and Ekert, and Duan and Guo were cast into a more general setting by P ...
Decoherence-free Subspaces
... A decoherence-free subspace (DFS) is a subspace of a system's Hilbert space that is invariant to non-unitary dynamics ... Decoherence creates problems in this regard by causing loss of coherence between the quantum states of a system and therefore the decay of their interference terms, thus leading to loss of information from the (open ...
