... are reversible, even though mixed states are involved. Finally we will consider operations without free noisy ancillas. Then the mixed states have to be created from pure states by partial trace, which introduces irreversibility. We discuss the implications of our results on understanding entangleme ...

While the QD1 resonance fluorescence plateau exhibits standard fine-structure-split lines of the neutral exciton, the QD2 plateau presents a unique signature of degenerate diagonal transitions: Instead of four resonance fluorescence lines visible only near the edges of the plateau due to sp ...
