中文摘要	two kinds of quantum computation systems using artificial molecules: quantum computer and quantum analog computer are described. the artificial molecule consists of two or three coupled quantum dots stacked along z direction and one single electron, in quantum computer, one-qubit and two-qubit gates are constructed by one molecule and two molecules, respectively. the coupling between two qubits in a quantum gate can be controlled by thin film electrodes. we also constructed a quantum analog computer by designing a three-dot molecule network and mapping a graph 3-colorability problem onto the network. the ground-state configuration of the single electrons in the network corresponds to one of the problem solutions, we numerically study the operations of the two kinds of the quantum computers and demonstrate that they quantum gates can perform the quantum computation and solve complex problems.
