Decoherence models and their effects on quantum maps and algorithms
Mario Leandro Aolita, Marcos Saraceno
In this work we study several models of decoherence and how different quantum maps and algorithms react when perturbed by them. Following closely Ref. [1], generalizations of the t…
Models of Diffusive Noise on the Sphere
M. E. Spina, M. Saraceno
We analyze Haake et al. method for coarse graining quantum maps on the sphere from the point of view of realizable physical quantum operations achieved with completely positive sup…
Tomography and spectroscopy as quantum computations
Cesar Miquel, Juan Pablo Paz, Marcos Saraceno +3
Determining the state of a system and measuring properties of its evolution are two of the most important tasks a physicist faces. For the first purpose one can use tomography, a m…
Exact and semiclassical Husimi distributions of Quantum Map Eigenstates
M. Saraceno, A. G. Monastra
The projector onto single quantum map eigenstates is written only in terms of powers of the evolution operator, up to half the Heisenberg time, and its traces. These powers are sem…
