Entanglement of two blocks of spins in the critical Ising model
P. Facchi, G. Florio, C. Invernizzi +1
We compute the entropy of entanglement of two blocks of L spins at a distance d in the ground state of an Ising chain in an external transverse magnetic field. We numerically study…
Optimal quantum estimation in spin systems at criticality
Carmen Invernizzi, Michael Korbman, Lorenzo Campos Venuti +1
It is a general fact that the coupling constant of an interacting many-body Hamiltonian do not correspond to any observable and one has to infer its value by an indirect measuremen…
Effect of noise and enhancement of nonlocality in on/off photodetection
Carmen Invernizzi, Stefano Olivares, Matteo G. A. Paris +1
Nonlocality of two-mode states of light is addressed by means of CHSH inequality based on displaced on/off photodetection. Effects due to non-unit quantum efficiency and nonzero da…
