(a) Echt 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 rein 16 polarization settings and using a maximum likelihood method. The measurements of the FSS are carried out with a https://whitneyc851fgh9.angelinsblog.com/profile
