Universal extensions of restricted classes of quantum operations
Michał Oszmaniec, Zoltán Zimborás
For numerous applications of quantum theory it is desirable to be able to apply arbitrary unitary operations on a given quantum system. However, in particular situations only a sub…

Estimation of gradients in quantum metrology
Sanah Altenburg, Michał Oszmaniec, Sabine Wölk +1
We develop a general theory to estimate magnetic field gradients in quantum metrology. We consider a system of particles distributed on a line whose internal degrees of freedom…

Multipartite quantum correlations: symplectic and algebraic geometry approach
A. Sawicki, T. Maciążek, M. Oszmaniec +3
We review a geometric approach to classification and examination of quantum correlations in composite systems. Since quantum information tasks are usually achieved by manipulating…
