(Color online) (a) Schematic diagram of a possible experimental setup: after photocounts are recorded, the measurement outcome (∣↑⟩ or ∣↓⟩) is decided based on whether . (b) Level scheme corresponding to each of the two subspaces, “+” and “−.” Optical transitions are induced by two lasers (blue arrows) and two degenerate cavity modes (red). The scheme relies on the Raman transitions between and that involve trion states , and are induced by light with polarization (solid arrows). All other virtual processes (see, e.g., dotted arrows) are very off-resonant.

(Color online) Simulated time evolution under the effect of two laser pulses, with frequencies (light gray area) and (dark gray), for (a) and (b). The curves show the occupations of (red line), (blue), the trion manifold (black dotted), and the “−” subspace (black dashed). The solid black line in panel (b) corresponds to . Figure inset: photon occupations for and , for (solid lines) and (dotted). The parameters are , , , , , , and .
