We make a numerical study of decoherence on the teleportation algorithm implemented in a linear chain of three nuclear spins system. We study different types of environments, and we determine the associated decoherence time as a function of the dissipative parameter. We found that the dissipation parameter to get a well defined quantum gates (without significant decoherence) must be within the range of γ≤4×10-4 for not thermalized case, which was determined by using the purity parameter calculated at the end of the algorithm. For the thermalized case the decoherence is stablished for very small dissipation parameter, making almost not possible to implement this algorithm for not zero temperature.
Asplenium nidus L. commonly called as Bird’s Nest
Fern, is a threatened, ornamental fern, which is widely used as
novel foliage ornamental plant and local people use it in worship. The taxon is threatened due to over
destruction and genetic barriers. To understand the constraints in the
regeneration, reproductive biology studies are made. It is observed that more sporophytes are produced in composite
population (13.3%) in comparison to isolate population (10%). This pattern is
suggestive of the fact that the parental sporophyte is heterozygous for recessive sporophytic lethal. On
the basis of the results obtained A. nidus was initially adapted for
outbreeding with the capacity for considerable amount of inbreeding. The low
potential of sporophyte production in isolate gametophyte could be the constitution
of the zygotic genotype.
