Privatization process of educational systems
Las políticas neoliberales, impulsadas por el FMI, OCDE, OMC y UE, desarrollan una
ofensiva contra los servicios sociales a fin de reducir el gasto público y proceder a su progresiva
privatización. Esta política también afecta a los sistemas de enseñanza. Las continuas
«reformas» educativas se orientan hacia una redefinición de los fines de la educación. El
Estado español no se ha sustraído de tales influencias. El mantenimiento de los privilegios
confesionales y de un sistema fragmentado en diversas redes de enseñanza, le permiten partir
con ventaja para el nuevo impulso privatizador generalizado. Además de severas reducciones
presupuestarias, se avanza hacia la desregulación del sistema educativo y a relegar el sector
público a un papel subsidiario dentro de un mercado diferenciado de ofertas y demandas
educativas. La LOMCE del ministro Wert profundiza esa orientación y las consiguientes
desigualdades sociales.The neoliberal policies carried out by the
IMF, the OECD, the WTO or the EU institutions, have been launching an offensive against
social services, in order to reduce public spending and to privatize our social system. This
policy also affects our educational systems. The continuing educational reforms tend to
redefine the goals of education. The Spanish State has been no exception to these influences.
The continuation of confessional privileges and a system divided in different networks
of education have created a favorable atmosphere for the new and widespread drive for
privatization. Apart from severe budget reductions, we move towards a deregulation of the
educational system, which will push our public sector into the background of a differentiate
market of supply and demand of educational services. The LOMCE of Minister Wert
underpins this approach, as well as the resulting social inequalities

Entanglement, quantum phase transitions and quantum algorithms
The work that we present in this thesis tries to be at the crossover of
quantum information science, quantum many-body physics, and quantum field
theory. We use tools from these three fields to analyze problems that arise in
the interdisciplinary intersection. More concretely, in Chapter 1 we consider
the irreversibility of renormalization group flows from a quantum information
perspective by using majorization theory and conformal field theory. In Chapter
2 we compute the entanglement of a single copy of a bipartite quantum system
for a variety of models by using techniques from conformal field theory and
Toeplitz matrices. The entanglement entropy of the so-called
Lipkin-Meshkov-Glick model is computed in Chapter 3, showing analogies with
that of (1+1)-dimensional quantum systems. In Chapter 4 we apply the ideas of
scaling of quantum correlations in quantum phase transitions to the study of
quantum algorithms, focusing on Shor's factorization algorithm and quantum
algorithms by adiabatic evolution solving an NP-complete and the searching
problems. Also, in Chapter 5 we use techniques originally inspired by
condensed-matter physics to develop classical simulations, using the so-called
matrix product states, of an adiabatic quantum algorithm. Finally, in Chapter 6
we consider the behavior of some families of quantum algorithms from the
perspective of majorization theory. The structure within each Chapter is such
that the last section always summarizes the basic results. Some general
conclusions and possible future directions are briefly discussed in Chapter 7.
Appendix A, Appendix B and Appendix C respectively deal with some basic notions
on majorization theory, conformal field theory, and classical complexity
theory.Comment: PhD Thesis, July 2006, University of Barcelona, 162 pages, compressed
