You seem to be ignoring the causality in there. :areyoucra Why is it surprising that the final configuration is determined by the initial configuration?
That's not quite right. If the computer can run forever, it can do things like "solve" the Halting problem. (Run the program you want to check.) It can't solve the HP in any finite amount of time, even if said amount is arbitarily large.
Godel's incompleteness theorem shows that no formal...
You are storing information that can be recovered in this setup. You recover it by either physically transporting the ion out of the trap, or teleporting its state into another part of the machine.
So "store" them without measuring them, e.g. with ion traps. A row of 1000 ion traps, each of which encodes a qubit via some property like spin counts as quantum RAM in my book.
I'm asking what's impossible in principle about a machine which carries quantum states around in exactly the same way that a modern processor/memory carries around classical states.
When you're completely done and want to write something out to an output device, yes. There's no reason why your "RAM" can't store qubits, other than engineering.
...Why not? Why can't I have a programming language that has quantum objects as data structures?
There's no physical requirement for that. It's merely very difficult to engineer a stable qubit register.
(Normal service may be resumed when I don't have code to write.)
In my course, Computer Science 11001 (as it was designated) was the basics of Java programming, including the semantics of objects, instances and static data. Of course, they were teaching the semantics to the humans, and so didn't use that particular word, but that's what they explained - what...
So, executing instructions that have the structure and semantics of object association does not mean you're actually associating objects...
Why not?
Consciousness itself isn't difficult. (Ohai, 'this' pointers!) It's all the background knowledge you need to understand what space is,
