Tensorial characterization and quantum estimation of weakly entangled qubits
P. Aniello, J. Clemente-Gallardo, G. Marmo +1
In the case of two qubits, standard entanglement monotones like the linear entropy fail to provide an efficient quantum estimation in the regime of weak entanglement. In this paper…
From Geometric Quantum Mechanics to Quantum Information
P. Aniello, J. Clemente-Gallardo, G. Marmo +1
We consider the geometrization of quantum mechanics. We then focus on the pull-back of the Fubini-Study metric tensor field from the projective Hibert space to the orbits of the lo…
Classical Tensors and Quantum Entanglement II: Mixed States
P. Aniello, J. Clemente-Gallardo, G. Marmo +1
Invariant operator-valued tensor fields on Lie groups are considered. These define classical tensor fields on Lie groups by evaluating them on a quantum state. This particular cons…
Classical Tensors and Quantum Entanglement I: Pure States
P. Aniello, J. Clemente-Gallardo, G. Marmo +1
The geometrical description of a Hilbert space asociated with a quantum system considers a Hermitian tensor to describe the scalar inner product of vectors which are now described…
Classical tensors from quantum states
P. Aniello, G. Marmo, G. F. Volkert
The embedding of a manifold M into a Hilbert-space H induces, via the pull-back, a tensor field on M out of the Hermitian tensor on H. We propose a general procedure to compute the…
