    "abstract": "In this paper, we studied the inter-valley interactions between the orbital\nfunctions associated with multi-valley of silicon (Si) quantum dots. Numerical\ncalculations show that the inter-valley coupling between orbital functions\nincreases rapidly with an applied electric field. We also considered the\npotential applications to the quantum bit operation utilizing controlled\ninter-valley interactions. Quantum bits are the multi-valley symmetric and\nanti-symmetric orbitals. Evolution of these orbitals would be controlled by an\nexternal electric field which turns on and off the inter-valley interactions.\nEstimates of the decoherence time are made for the longitudinal acoustic phonon\nprocess. Elementary single and two qubit gates are also proposed.",
