Quantum entanglement
All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Entanglement in many-body systems
Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

Entanglement in indistinguishable particle systems
For systems consisting of distinguishable particles, there exists an agreed upon notion of
entanglement which is fundamentally based on the possibility of addressing individually …

Entanglement in a simple quantum phase transition
What entanglement is present in naturally occurring physical systems at thermal
equilibrium? Most such systems are intractable and it is desirable to study simple but …

Entanglement of indistinguishable particles shared between two parties
Using an operational definition we quantify the entanglement, EP, between two parties who
share an arbitrary pure state of N indistinguishable particles. We show that EP≤ EM, where …

Quantum correlations in systems of indistinguishable particles
We discuss quantum correlations in systems of indistinguishable particles in relation to
entanglement in composite quantum systems consisting of well separated subsystems. Our …

Quantum entanglement in fermionic lattices
P Zanardi - Physical review A, 2002 - APS
The Fock space of a system of indistinguishable particles is isomorphic (in a nonunique
way) to the state space of a composite, ie, many modes, quantum system. One can then …

Indistinguishability of elementary systems as a resource for quantum information processing
Typical elements of quantum networks are made by identical systems, which are the basic
particles constituting a resource for quantum information processing. Whether the …

General criterion for the entanglement of two indistinguishable particles
We relate the notion of entanglement for quantum systems composed of two identical
constituents to the impossibility of attributing a complete set of properties to both particles …
