Identifier: http://hdl.handle.net/1959.14/1044071
Description: We investigate general optical interferometry in stationary spacetimes focusing on quantum-optical experiments in near-Earth environments. We provide a rigorous expression for the gravitationally indu ... More

Identifier: http://hdl.handle.net/1959.14/188551
Description: Entanglement does not describe all quantum correlations and several authors have shown the need to go beyond entanglement when dealing with mixed states. Various different measures have sprung up in t ... More

Identifier: http://hdl.handle.net/1959.14/200840
Description: One of the best signatures of nonclassicality in a quantum system is the existence of correlations that have no classical counterpart. Different methods for quantifying the quantum and classical parts ... More

Identifier: http://hdl.handle.net/1959.14/134583
Description: We show that the ability to create entanglement is necessary for execution of bipartite quantum gates even when they are applied to unentangled states and create no entanglement. Starting with a simpl ... More
