Abstract: It was theoretically proposed that a forward-biased p-n junction with a superconducting layer (P-N-S), would produce pure, polarization entangled photons due to inherent spin-singlet pairing of electrons. However, any heterostructure interface generically induces Rashba spin-orbit… read more here.
