An intuitive scheme for the restoration of entanglement for polarization-entangled photons emitted from quantum dots with non-vanishing fine structure splitting

Simone Varo, Gediminas Juska, Emanuele Pelucchi

Generation of polarization-entangled photons from quantum dots via the biexciton-exciton recombination cascade is complicated by the presence of an energy spitting between the inte…
