> When you turn the computer off, it remembers what's on your harddrive.
Weird analogy. The computer doesn't remember – the individual storage units on a hard drive don't care whether the machine around them has power or not They are indifferent to what's going on in the system which contains them as opposed to, say, the storage units in DRAM. Are you trying to say that at the moment all qubits we've made behave like the storage units in DRAM? In other words, while the system that contains them is powered on they remain in the same state but when the power is removed they become disordered? Aren't qubits an abstraction? I mean, qubit : bit :: qubit storage unit X : harddrive bit – or – qubit : bit :: qubit storage unit Y : DRAM bit – see what I mean?
