    "abstract": "Using electrostatic gates to control the electron positions, we present a new\ncontrolled-NOT gate based on quantum dots. The qubit states are chosen to be\nthe spin states of an excess conductor electron in the quantum dot; and the\nmain ingredients of our scheme are the superpositions of space-time paths of\nelectrons and the effect of Coulomb blockade. All operations are performed only\non individual quantum dots and are based on fundamental interactions. Without\nresorting to spin-spin terms or other assumed interactions, the scheme can be\nrealized with a dedicated circuit and a necessary number of quantum dots. Gate\nfidelity of the quantum computation is also presented.",
