Abstrakt

Generace jednotlivých fotonů má v rámci využití kvantových technologií širokou škálu uplatnění. Cílem práce bude seznámit se s možnostmi a způsoby generování jednotlivých fotonů a s jejich charakterizací. Současně bude sestavován HBT interferometr a dle možností provedena experimentální charakterizace vybraného dostupného zdroje jednotlivých fotonů.

Abstract

Quantifying the quantum resources is a formidable task in the framework of quantum information theory. In view of this, different quantum resources have been identified such as entanglement, quantum discord, measurement-induced nonlocality, imaginarity etc. Among them, the imaginarity is a primary concept in quantum mechanics and its  resource theory is also established very recently.  In the resource theory of imaginarity, the free states are called real states, and their density matrices are real under a set of fixed reference bases. The free operations are called real operations.

The present study motivate to identify new measure of imaginarity.

Abstract

When the physical properties of the system approach a macroscopic level, the Milburn formulation  aims to adjust Schrödinger’s equation so that coherence is lost automatically. Intrinsic decoherence is the term for this type of decoherence.  Thus, Milburn equations are used to explore the decoherence caused here due to the loss of coherence between the sub-systems of a composite state and not caused by the environment. While the master equations prompt us to experience the decoherence effects in quantum systems caused by the environmental interaction.

The present study the influence of intrinsic decoherence on quantum resources.
