Optimal estimation of losses at the ultimate quantum limit with non-Gaussian states
G. Adesso, F. Dell'Anno, S. De Siena +2
We address the estimation of the loss parameter of a bosonic channel probed by arbitrary signals. Unlike the optimal Gaussian probes, which can attain the ultimate bound on precisi…
Hierarchies of Geometric Entanglement
M. Blasone, F. Dell'Anno, S. De Siena +1
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of elementary subsystems, they are defined as the distances from the sets of …
Multipartite entangled states in particle mixing
M. Blasone, F. Dell'Anno, S. De Siena +2
In the physics of flavor mixing, the flavor states are given by superpositions of mass eigenstates. By using the occupation number to define a multiqubit space, the flavor states c…
Determination of ground state properties in quantum spin systems by single qubit unitary operations and entanglement excitation energies
S. M. Giampaolo, F. Illuminati, P. Verrucchi +1
We introduce a method for analyzing ground state properties of quantum many body systems, based on the characterization of separability and entanglement by single subsystem unitary…
