Quantum discord, EPR steering and Bell-type correlations for secure CV quantum communications
Quantum states can be correlated in ways beyond what is possible for classical states. These correlations are considered as the main resource for quantum computation and communication tasks. In this thesis, I present my studies on the different forms of Quantum Correlations known as "Quantum …

Phase Transitions in Dipole-Dipole Interacting Atomic Systems
… This suggests that the phase transition is of quantum nature. Additionally, the quantum discord of the system is computed. By the use of the full permutation invariance of the system, we show that the numerical complexity in computing quantum discord is significantly reduced. The result …

Quantum correlations and measurements in tri-partite quantum systems.
… A,B might or might not be entangled. By using quantum discord, which measures the quantumness of correlations, it is shown that there are quantum correlations between oscillators A,B and after the measurements in both cases of selective and non-selective measurements, oscillators A,B and A,C …

Enforcing nonclassicality in medium-scale quantum systems
… <br/><br/>The first aspect is macroscopic quantumness, a field which considers the properties of macroscopic superpositions. The various measures of macroscopicity are reviewed. An optomechanical system is described which enables us to study nonclassicality in macroscopic mechanical …

Coherent control of polarized neutron interferometry
… First, we explore applications of quantum information processing (QIP) to magnetic materials characterization using polarized neutron interferometry (NI). We describe a split path spin-based interferometer geometry that uses the Bragg interferometer to separate two paths where spin …

Relativistic Quantum Tasks
Quantum mechanics, which describes the behaviour of matter and energy on very small scales, is one of the most successful theories in the history of science. Einstein's theory of special relativity, which describes the relationship between space and time, is likewise a highly successful and widely …
