Reconstructing the whole from its parts
Daniel Uzcátegui Contreras, Dardo Goyeneche
The quantum marginal problem consists in deciding whether a given set of marginal reductions is compatible with the existence of a global quantum state or not. In this work, we for…
Locality of percolation for graphs with polynomial growth
Daniel Contreras, Sébastien Martineau, Vincent Tassion
Schramm's Locality Conjecture asserts that the value of the critical percolation parameter of a graph satisfying depends only on its local structure. In this note, we…
Design of optimization tools for quantum information theory
Daniel Uzcategui Contreras
In this thesis, we present optimization tools for different problems in quantum information theory. First, we introduce an algorithm for quantum estate estimation. The algorithm co…
Supercritical percolation on graphs of polynomial growth
Daniel Contreras, Sébastien Martineau, Vincent Tassion
We consider Bernoulli percolation on transitive graphs of polynomial growth. In the subcritical regime (), it is well known that the connection probabilities decay exponenti…
Fast and simple quantum state estimation
Daniel Uzcategui Contreras, Gabriel Senno, Dardo Goyeneche
We present an iterative method to solve the multipartite quantum state estimation problem. We demonstrate convergence for any informationally complete set of generalized quantum me…
Circulant matrices with orthogonal rows and off-diagonal entries of absolute value
Daniel Uzcátegui Contreras, Dardo Goyeneche, Ondřej Turek +1
It is known that a real symmetric circulant matrix with diagonal entries , off-diagonal entries and orthogonal rows exists only of order (and trivially of ord…
