Serially Factoring large prime numbers --- Shor's algorithm modification



Hi,
I'm sorry I got carried away.
I believe Shor's algorithm uses a quantum computer to factor large prime numbers product. To crack the RSA algorithm you need to factor the product of two large prime numbers.

Now for that you do not need a large number of qubits quantum computer.

Dwave Systems (http://www.dwavesys.com) claims it has a 16 bit quantum computer.

How does one use that 16 bit quantum computer to factor large prime numbers to crack the RSA algorithm (or indeed even a "small number of bits" quantum computer which has say 10^300 states which is larger than the number of protons in the entire known Universe).

You can get Shor's algorithm from Wikipedia or arxiv.org
Take a look at Grover's algorithm too.

1. Use a recursive, output-feedforward algorithm as below.

1. Feed the problem into the "X" qubit quantum computer.
2. When the X qubits settle down, you have obtained the first X bits of the solution.

RECURSION, FEED-FORWARD
1A. Feed the problem into the "X" qubit quantum computer along with the first X bits of the solution.
1B. When the X qubits settle down you have obtained the second X qubits of the solution.

RECURSION, Feed-forward
1C. Feed the problem into the "X" qubit quantum computer along with the first X qubits of the solution and the second X qubits of the solution.
2C. When the X qubits settle down you have obtained the third X qubits of the solution.

Repeat the recursion and feedforward above until the entire solution is obtained.
