As an example, a single photon can also be in an (uncountable) infinity of positions, but that is not enough to build a quantum computer. If you want countably infinite levels, you can also have those with a single photon, via its orbital angular momentum. | |

Also, in case you weren't aware, there is also a dedicated quantumcomputing stackexchange where you can ask these sorts of questions. | |
