    "abstract": "We present an all-optical implementation of quantum computation using\nsemiconductor quantum dots. Quantum memory is represented by the spin of an\nexcess electron stored in each dot. Two-qubit gates are realized by switching\non trion-trion interactions between different dots. State selectivity is\nachieved via conditional laser excitation exploiting Pauli exclusion principle.\nRead-out is performed via a quantum-jump technique. We analyze the effect on\nour scheme\u0027s performance of the main imperfections present in real quantum\ndots: exciton decay, hole mixing and phonon decoherence. We introduce an\nadiabatic gate procedure that allows one to circumvent these effects, and\nevaluate quantitatively its fidelity.",
