Statistics of orbital entanglement production in quantum-chaotic dots
Victor A. Gopar, Diego Frustaglia
The production of orbitally entangled electrons in quantum-chaotic dots is investigated from a statistical point of view. The degree of entanglement is quantified through the concu…
Multi-channel architecture for electronic quantum-Hall interferometry
Vittorio Giovannetti, Fabio Taddei, Diego Frustaglia +1
We propose a new architecture for implementing electronic interferometry in quantum Hall bars. It exploits scattering among parallel edge channels. In contrast to previous developm…
Characterizing electron entanglement in multiterminal mesoscopic conductors
Vittorio Giovannetti, Diego Frustaglia, Fabio Taddei +1
We show that current correlations at the exit ports of a beam splitter can be used to detect electronic entanglement for a fairly general input state. This includes the situation w…
Theoretical study of the conductance of ferromagnetic atomic-sized contacts
M. Häfner, J. K. Viljas, D. Frustaglia +4
Recently, different experiments on the transport through atomic-sized contacts made of ferromagnetic materials have produced contradictory results. In particular, several groups ha…
Electronic Hong-Ou-Mandel interferometer for multi-mode entanglement detection
Vittorio Giovannetti, Diego Frustaglia, Fabio Taddei +1
We show that multi-mode entanglement of electrons in a mesoscopic conductor can be detected by a measurement of the zero-frequency current correlations in an electronic Hong-Ou-Man…
Entanglement production in chaotic quantum dots subject to spin-orbit coupling
Diego Frustaglia, Simone Montangero, Rosario Fazio
We study numerically the production of orbital and spin entangled states in chaotic quantum dots for non-interacting electrons. The introduction of spin-orbit coupling permit us to…
