Why entanglement of formation is not generally monogamous
Unlike correlation of classical systems, entanglement of quantum systems cannot be distributed at will: if one system A is maximally entangled with another system B, it cannot be entangled at all with a third system C. ...
Multipartite quantum correlations in open quantum systems
In this paper, we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined for quantum discord (QD), geometric quantum ...
Entanglement and the process of measuring the position of a quantum particle
We explore the entanglement-related features exhibited by the dynamics of a composite quantum system consisting of a particle and an apparatus (here referred to as the "pointer") that measures the position of the particle. ...
Quantum entanglement of helium-like systems with varying-Z: Compact state-of-the-art CI wave functions
(Iop Publishing, 2015-07-17)
In this work we have performed state-of-the-art configuration-interaction (CI) calculations to determine the linear and von Neumann entanglement entropies for the helium-like systems with varying nuclear charge Z in the ...
Quantum entanglement and information: The effect of entropy revisited
In non-extensive statistical mechanics , it is a nonsense statement to say that the entropy of a system is extensive (or not), without mentioning a law of composition of its elements. In this theory quantum correlations ...
Entanglement and control operations in Heisenberg 3-D interactions of two qubits
(Revista Mexicana de Física, 2010)
Dynamics of entanglement in systems of identical fermions undergoing decoherence
(American Physical Society, 2015-03)
Information that is stored in quantum-mechanical systems can be easily lost because of the interaction with the environment in a process known as decoherence. Possible physical implementations of many processes in quantum ...
