    "abstract": "Based on an idea that spatial separation of charge states can enhance quantum\ncoherence, we propose a scheme for quantum computation with quantum bit (qubit)\nconstructed from two coupled quantum dots. Quantum information is stored in\nelectron-hole pair state with the electron and hole locating in different dots,\nwhich enables the qubit state being very long-lived. Universal quantum gates\ninvolving any pair of qubits are realized by coupling the quantum dots through\ncavity photon which is a hopeful candidate to transfer long-range information.\nOperation analysis is carried out by estimating the gate time versus the\ndecoherence time.",
