Entanglement of Electrons Field-Emitted from a Superconductor
Kazuya Yuasa, Paolo Facchi, Rosario Fazio +4
Under appropriate circumstances the electrons emitted from a superconducting tip can be entangled. We analyze these nonlocal correlations by studying the coincidences of the field-…
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…
Bang-Bang control of a qubit coupled to a quantum critical spin bath
Davide Rossini, Paolo Facchi, Rosario Fazio +5
We analytically and numerically study the effects of pulsed control on the decoherence of a qubit coupled to a quantum spin bath. When the environment is critical, decoherence is f…
