Spins extracted from fermionic states and their entanglement properties
Filippo Troiani, Andrea Secchi, Stefano Pittalis
We investigate the spin states obtained by extracting electrons from closed-shell fermionic states. A partition of the system is defined through the introduction of the extract…

Giant Rabi frequencies between qubit and excited hole states in silicon quantum dots
E. Fanucchi, G. Forghieri, A. Secchi +2
Holes in Si quantum dots are being investigated for the implementation of electrically addressable spin qubits. In this perspective, the attention has been focused on the electric-…

Genuine multipartite entanglement from many-electron systems
Filippo Troiani, Celestino Angeli, Andrea Secchi +1
We demonstrate that, contrary to common wisdom, genuine multipartite entanglement (GME) can be abundantly generated from simple non-correlated many-electron states. We show that th…
