Multi-distributed Entanglement in Finitely Correlated Chains
F. Benatti, B. C. Hiesmayr, H. Narnhofer
The entanglement-sharing properties of an infinite spin-chain are studied when the state of the chain is a pure, translation-invariant state with a matrix-product structure. We stu…
Criteria for the entanglement of composite systems of identical particles
GianCarlo Ghirardi, Luca Marinatto
We identify a general criterion for detecting entanglement of pure bipartite quantum states describing a system of two identical particles. Such a criterion is based both on the co…
Comment on "Bell's Theorem without Inequalities and without Alignments"
Luca Marinatto
In this Comment we show that Cabello's proof of Bell's theorem without inequalities [Phys. Rev. Lett. 91, 230403 (2003)] does not exhibit two of the three "remarkable properties" w…
Coadjoint Orbits, Spin and Dequantization
D. Mauro
In this Letter we propose two path integral approaches to describe the classical mechanics of spinning particles. We show how these formulations can be derived from the associated…
Towards Quantum Superpositions of a Mirror: an Exact Open Systems Analysis - Calculational Details
S. L. Adler, A. Bassi, E. Ippoliti
We give details of calculations analyzing the proposed mirror superposition experiment of Marshall, Simon, Penrose, and Bouwmeester within different stochastic models for state vec…
Geometric Dequantization
A. A. Abrikosov, E. Gozzi, D. Mauro
Dequantization is a set of rules which turn quantum mechanics (QM) into classical mechanics (CM). It is not the WKB limit of QM. In this paper we show that, by extending time to a…
