Examples of decoherence

decoherence isn’t in the Cambridge Dictionary yet. You can help!
Decoherence in quantum walks to the coefficient yb in the summation are maintained.
A lower bound on the mixing time for large decoherence rate p can be derived as follows.
Another goal of the type system is to control decoherence, and this is supported by introducing a judgement and derivation rules for orthogonality of state-spaces.
As remarked, the main argument against non-trivial quantum effects in biology is decoherence.
In typical biochemical environments decoherence times are likely to be 5reaction times.
This relation models the transformations that can happen in the presence of decoherence and imprecision of physical operations.
However, mechanisms are known that can greatly extend decoherence times.
The decoherence operators in equation (85) project the walker onto one of the vertices of the hypercube chosen uniformly at random.
This concludes our overview of decoherence in continuous-time walks.
Some clues about how decoherence might be evaded are discussed.
Decoherence on the coin only does not produce a top-hat distribution, instead the distribution develops a cusp as it passes from quantum to classical.
Indeed, the first suggested application of a quantum walk in a physical system was to test decoherence rates in a single trapped ion.
It is obvious that decoherence must do this, since high decoherence rates reproduce the classical random walk, which has this property.
They augment this with numerical studies showing a minimum mixing time for intermediate decoherence rates.
This shows that the effects of decoherence are quite robust, being insensitive to the precise way in which it is applied.
The dissipation was numerically computed using the method of quantum trajectories, which enables us to study a quantum computer undergoing decoherence for relatively long times.
The second type is external non-unitary errors, which correspond to coupling to the external world and are usually described as 'decoherence'.
We now show that with the model of decoherence described above each dimension still behaves independently.
First we consider decoherence of the coin only.
