  We propose a new kind of qubits composed of electric dipolar molecules. The
electric dipolar molecules in an external uniform electric field will take
simple harmonic oscillations, whose quantum states belonging to the two lowest
energy levels act as the states |0>,|1> of a qubit. The qubits' excited states
have a very long mean life time more than 70ms.We can perform quantum
computations by manipulating the qubits of electric dipolar molecules just like
those of neutral atoms. When the qubits are used for quantum computations, the
dipolar moments' orientations will harmonically oscillate along an external
electric field and they will not change the directions: along or against the
electric field, so the qubits can be large-scalely manufactured in graphene
solid.
