Contextuality and Quantum Discord
Asma Al-Qasimi
One of the defining differences between classical and quantum systems is how measurements affect them. Here, we compare the approaches of contextuality and quantum discord in captu…
Emergence of singularities from decoherence: Quantum catastrophes
Aaron Z. Goldberg, Asma Al-Qasimi, J. Mumford +1
We use a master equation to study the dynamics of two coupled macroscopic quantum systems (e.g.\ a Josephson junction made of two Bose-Einstein condensates or two spin states of an…
Quantum properties and dynamics of X states
Nicolás Quesada, Asma Al-Qasimi, Daniel F. V. James
X states are a broad class of two-qubit density matrices that generalize many states of interest in the literature. In this work, we give a comprehensive account of various quantum…
A Comparison of the Attempts of Quantum Discord and Quantum Entanglement to Capture Quantum Correlations
Asma Al-Qasimi, Daniel F. V. James
Measurements of Quantum Systems disturb their states. To quantify this non-classical characteristic, Zurek and Ollivier introduced the quantum discord, a quantum correlation which…
Nonexistence of Entanglement Sudden Death in High NOON States
Asma Al-Qasimi, Daniel F. V. James
We study the dynamics of entanglement in continuous variable quantum systems (CVQS). Specifically, we study the phenomena of Entanglement Sudden Death (ESD) in general two-mode-N-p…
Do all states undergo sudden death of entanglement at finite temperature?
Asma Al-Qasimi, Daniel F. V. James
In this paper we consider the decay of quantum entanglement, quantified by the concurrence, of a pair of two-level systems each of which is interacting with a reservoir at finite t…
