I think I understand quantum superposition and entanglement, and a qubit. I just finished reading Scott Aaronson's brilliant blog post "Shor I'll Do It" that allowed me to understand Shor's Algorithm and how it relates to QM. But now I'm missing the next step. How does one "wire up" a number of qubits to implement Shor's algorithm and apply it to find the period of a specific key? Can anyone steer me to a reference that would explain that please? My mind wants to make an analogy to the earliest computers like the IBM 650 when programming consisted of plugging patch cords into a panel. photo Daniel Sancho - Flickr: Panel IBM p.s. I guessed that this question would be better in the QM forum than the programming and computer science forum.
