US Patent 7737432 - Coupled quantum dot computer

This patent from the National Research Council of Canada teaches a variation of qubits used in quantum computing which provide the advantage of a long coherence time and voltage control of the qubit state. Claim 1 reads:

1. A computing element for a quantum computer comprising at least three coupled quantum dots that can adopt more than one collective state, and at least a first gate means for applying an electric field to manipulate the collective state of said coupled quantum dots, wherein said quantum dots are arranged in a triangular formation.
