    Please see my recent posts on comp.ai.philosophy for a full treatment.
    Check::
    http://alumni.imsa.edu/~matth/quant/299/paper/node1.html
    for a good discussion of Shor's algorithm which can be used to crack
    the RSA algorithm used for securing the Internet (check the Wikipedia
    and arxiv.org for more on Shor's algorithm and Grover's algorithm and
    quantum computing).

    Check IBM for its 7 qubit quantum computer and http://www.dwavesys.com
    for its 16 qubit quantum computer. The Japanese are building quantum
    computers using superconductors (at perhaps room temperature).

    Now, how to use a small number of qubit quantum computer (say X
    qubits).

    Step 1A. Feed the problem into the quantum computer along with 0
    output bits.
    Step 1B. The X qubit problem settles into the first X bits of the
    solution.

    RECURSION AND FEED-FORWARD
    Step 2A. Feed the problem and the FIRST X qubits of the solution.
    Step 2B. Obtain the second X qubits of the solution.

    DO RECURSION AND FEED FORWARD REPEATELY.
    Step 3A. Feed the problem and the FIRST and SECOND qubits of the
    solution.
    Step 3B. Obtain the THIRD X bits of the solution

    Continue the recursion and feed forward above until the entire answer
    is obtained. (say the factorization of the product into Primes to
    break RSA ENcryption, or the language problem, or travelling salesman
    problem or whatever).
