a, Single quantum dot biexciton (XX) and exciton (X) spin states. Indicated are the two possible optical recombination paths in the biexciton–exciton cascade. The anisotropic electron–hole exchange splitting δ typically allows us to distinguish between both paths. b,  A QDM allows for a modified spin level structure in the biexciton–exciton cascade. The use of two additional exciton spin states, | and |, without anisotropic electron–hole spin exchange is being proposed to erase the which-path information.

Relevant charge configurations of a biexciton and an exciton in a QDM designed for hole tunneling. The interdot biexciton can be selectively excited via a two-photon, or biphotonic, transition. The emission of the first photon (Pl1) creates an interdot exciton. The charge separation in the interdot exciton causes a vanishing anisotropic electron–hole spin exchange required to erase the which-path information. A relaxation process involving the emission of a phonon turns the interdot exciton into an intradot exciton. The recombination of the intradot exciton yields the second photon (Pl2) of the entangled photon pair.

a, The molecular biexciton can be resonantly excited via a degenerate biphotonic transition without the excitation being degenerate with the emitted photons, Pl1 and Pl2. The excitation happens via a virtual exciton state at half the energy of the final biexciton state. Note that exciton and biexciton states are, in general, not energetically equidistant because of higher order Coulomb interactions. In order to test if the biphotonic transition can selectively excite the interdot biexciton spin singlet state, mapping the tunnel resonance of the molecular biexciton is proposed. b, As shown previously, this can be achieved by embedding the QDM in a Schottky diode structure, which allows for the free shifting of both dots’ energy levels with respect to each other. c, An electric field dispersed PL spectrum of the Pl1 transition in the vicinity of the biexciton tunnel resonance obtained after nonresonant excitation. Both singlet and triplet states are detected. Under biphotonic excitation, we predict the triplet states not to be visible.
