Coherence computing
WebCache coherence. An illustration showing multiple caches of some memory, which acts as a shared resource. Incoherent caches: The caches have different values of a single address location. In computer architecture, cache coherence is the uniformity of shared resource data that ends up stored in multiple local caches.

WebT 2 generally refers to the measurement of the coherence of the qubit with respect to its dephasing (that's a rotation through the 0 - 1 axis of the Bloch sphere for those of us visualizing). But sometime in the literature, it's called T 2 and other times it's referred to as T 2 ∗. The fact that it is never explained leads me to believe ... WebThis is where coherence is important for quantum computing. It is precisely because the system behaves as many different systems interfering all together that its description is …
Coherence is preserved under the laws of quantum physics. If a quantum system were perfectly isolated, it would maintain coherence indefinitely, but it would be impossible to manipulate or investigate it. See more Quantum decoherence is the loss of quantum coherence, the process in which a system's behaviour changes from that which can be explained by quantum mechanics to that which can be explained by classical … See more To examine how decoherence operates, an "intuitive" model is presented below. The model requires some familiarity with quantum theory … See more Decoherence represents an extremely fast process for macroscopic objects, since these are interacting with many microscopic … See more Quantitative measurement The decoherence rate depends on a number of factors, including temperature or uncertainty in position, and many experiments have … See more Decoherence can be modelled as a non-unitary process by which a system couples with its environment (although the combined system plus environment evolves in a unitary … See more Assume for the moment that the system in question consists of a subsystem A being studied and the "environment" $${\displaystyle \epsilon }$$, and the total Hilbert space is … See more Criticism of the adequacy of decoherence theory to solve the measurement problem has been expressed by Anthony Leggett.
