N2 - The authors propose an all-optical scheme to perform a nondemolition measurement of a single hole spin localized in a quantum-dot molecule. The latter is embedded in a microcavity and driven by two lasers. This allows them to induce Raman transitions which entangle the spin state with the polarization of the emitted photons. They find that the measurement can be completed with high fidelity on a time scale T∼ 102 ps, shorter than the typical decoherence time.
