    "abstract": "A potential scheme is proposed for realizing a two-qubit quantum gate in\nsemiconductor quantum dots. Information is encoded in the spin degrees of\nfreedom of one excess conduction electron of each quantum dot. We propose to\nuse two lasers, radiation two neighboring QDs, and tuned to blue detuning with\nrespect to the resonant frequencies of individual excitons. The two-qubit phase\ngate can be achieved by means of both Pauli-blocking effect and dipole-dipole\ncoupling between intermediate excitonic states.",
