I once read what I thought was an excellent explanation of the Quantum Processing theory, I'll try to reproduce it here.
Imagine an office building in which there is a single briefcase in one of the offices. It is not known which one.
In order to find the briefcase you would have to search room by room until it was found.
This is the way that modern computer systems work.
Now imagine if you were to temporarily produce clones of yourself whose count match the exact number of rooms in the building. Each of them could stand outside a room and all of them enter their room simultaneously. Then cause all of the clones that did not find the briefcase to disappear leaving only the clone with the find.
This is how I understand Quantum Computer to work.
The quantum states of n qubits are combined to produce 2^n unique simultaneous results. Then only the result that is correct is caused to remain.
Now for a Practical Application besides code breaking.
What about a memory system? If it was a 64 qubit system the following could take place:
Determine the address of the memory location by masking out the high order (HO) double word (dw)of the system, thereby determining the address in the low order (LO) dw, and mask out the LO dw to retrieve the instruction or data in the HO dw stored at that address.
Pardon my ascii art.
|-------------------------------64-------------- -----------------|
|---------------HO---------------||------------- -LO--------------|
|-------Instruction / Data---------||------------Address-----------|
If my understanding of the qubit system is correct then the only limit on the amount of memory in the system would be the address bus of the CPU. There would be no need for an array of memory cells ('chips') a single qubit register would provide all of the memory locations needed.
This assumes that the CPU processes 32 bit data and uses 32 bit addresses.
