(a) Tatsächlich and imaginary part of the two-photon density matrix reconstructed via quantum state tomography on quantum dot QD2. The matrix has been calculated out of biexciton–exciton (XX–X) cross-correlation measurements in 16 polarization settings and using a maximum likelihood method. By contrast, compartmental segregation is preserved and even reinforced. Strikingly, https://johnn395qrs4.bimmwiki.com/user
