Two Problems on Quantum Computing in Finite Abelian Groups

Ulises Pastor-Díaz, José M. Tornero

In the context of finite Abelian groups two problems are presented and solved using quantum computing techniques. The first is the well--known Hidden Subgroup Problem, originally s…

On the torsion growth in quadratic number fields for elliptic curves defined over the rationals

Sara Arias-de-Reyna, Miguel Pineda-Martín, José M. Tornero

Given an elliptic curve defined over the field of rational numbers, it is known how its torsion subgroup may grow when we make a base change to a quadratic number field. In this pa…

Onthe computation of the MED closure of a numerical semigroup

Jorge Jiménez Urroz, José M. Tornero

Maximally embedding dimension (MED) numerical semigroups are a wide and interesting family, with some remarkable algebraic and combinatorial properties. Associated to any numerical…

Further Applications of the Generalised Phase Kick-Back

Joaquín Ossorio-Castillo, Ulises Pastor-Díaz, José M. Tornero

In our previous work, we defined a quantum algorithmic technique known as the Generalised Phase Kick-Back, or , and analysed its applications in generalising some classical qu…

Quantum algorithms for the Sylvester denumerant and the numerical semigroup membership problem

J. Ossorio-Castillo, José M. Tornero

Two quantum algorithms are presented, which tackle well--known problems in the context of numerical semigroups: the numerical semigroup membership problem (NSMP) and the Sylvester…

On the Walsh and Fourier-Hadamard Supports of Boolean Functions From a Quantum Viewpoint

Claude Carlet, Ulises Pastor-Díaz, José María Tornero

In this paper, we focus on the links between Boolean function theory and quantum computing. In particular, we study the notion of what we call fully-balanced functions and analyse…

Hironaka's characteristic polygon and effective resolution of surfaces

R. Piedra, J. M. Tornero

Hironaka's concept of characteristic polyhedron of a singularity has been one of the most powerful and fruitful ideas of the last decades in singularity theory. In fact, since then…
