Quantum k-designs and weak randomness
Abstract:
Práce se zabývá šifrováním kvantové informace s použitím zdroje slabé náhodnosti. Šifrování v klasickém i kvantovém případě je popsáno jako geometrická transformace a jsou zkoumány kryptosystémy tvořené k-designy. Pro použitelnost takového systému je důležitá kvalita použité náhodnosti. Práce obsahuje přehled zdrojů slabé náhodnosti a zkoumá jak dobře je možno šifrovat kvantovou informaci při použití …moreAbstract:
In this thesis we will study encryption of single qubit of quantum information using a quantum $k$-design and a weak source of randomness. We will describe encryption as geometric transformation in both classical and quantum case and we will explore the quantum cryptosystems formed by k-designs. For reliability of such system the quality of supplied randomness is essential. We will provide a short …more
