Unveiling the geometric meaning of quantum entanglement: discrete and continuous variable systems
Arthur Vesperini, Ghofrane Bel-Hadj-Aissa, Lorenzo Capra +1
We show that the manifold of quantum states is endowed with a rich and nontrivial geometric structure. We derive the Fubini-Study metric of the projective Hilbert space of a multi-…
Entanglement and Quantum Correlation Measures from a Minimum Distance Principle
Arthur Vesperini, Ghofrane Bel-Hadj-Aissa, Roberto Franzosi
Entanglement, and quantum correlation, are precious resources for quantum technologies implementation based on quantum information science, such as, for instance, quantum communica…
The Berezinskii Kosterlitz Thouless phase transition is of second-order in the microcanonical ensemble
Ghofrane Bel-Hadj-Aissa, Matteo Gori
A paradigmatic example of a phase transition taking place in the absence of symmetry-breaking is provided by the Berezinkii-Kosterlitz-Thouless (BKT) transition in the two-dimensio…
Entanglement distance for arbitrary -qudit hybrid systems
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
The achievement of quantum supremacy boosted the need for a robust medium of quantum information. In this task, higher-dimensional qudits show remarkable noise tolerance and enhanc…
Geometrical aspects in the analysis of microcanonical phase-transitions
Ghofrane Bel-Hadj-Aissa, Matteo Gori, Vittorio Penna +2
In the present work, we discuss how the functional form of thermodynamic observables can be deduced from the geometric properties of subsets of phase space. The geometric quantitie…
High order derivatives of Boltzmann microcanonical entropy with an additional conserved quantity
Ghofrane Bel-Hadj-Aissa
In this article, using a known method, a computation is performed of the derivatives of the microcanonical entropy, with respect to the energy up to the 4-th order, using a Laplace…
