Quantum-Information Measure of Electron Localization
Stefano Pittalis, Filippo Troiani, Celestino Angeli +2
Understanding electron localization in molecules and materials plays a central role in electronic structure theory, and will increase in importance with the rise of data-driven app…
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…
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…
Entangled photon pairs from a quantum dot cascade decay: the effect of time-reordering
F. Troiani, C. Tejedor
Coulomb interactions between confined carriers remove degeneracies in the excitation spectra of quantum dots. This provides a which path information in the cascade decay of biexcit…
Quantum-tomography of entangled photon pairs by quantum-dot cascade decay
F. Troiani, J. I. Perea, C. Tejedor
We compute the concurrence of the polarization-entangled photon pairs generated by the biexciton cascade decay of a semiconductor quantum dot. We show how a cavity-induced increase…
Correlated photon-pair emission from pumped-pulsed quantum dots embedded in a microcavity
J. I. Perea, F. Troiani, C. Tejedor
We theoretically investigate the optical response of a quantum dot, embedded in a microcavity and incoherently excited by pulsed pumping. The exciton and biexciton transition are o…
