摘　　要：We analyze various possible superconducting pairing states and their relative stabilities in lightly doped graphene.It is shown that,when inter-sublattice electron-electron attractive interaction dominates and the Fermi level is close to the Dirac points,the system will favor intra-valley spin-triplet p+ip pairing state.Based on the novel pairing state,we further propose a scheme for doing topological quantum computation in graphene by engineering local strain fields and external magnetic fields.
