                                                                          You're saying that these qubits havea a superpoisition, where it contains more information than 1 or 0. Interpreting that information sounds like looking at a rainbow and asking "which ONE color is it?". In that case you either get a confusing answer from a qubit, or most of the information is useless in it.
                                                                          You also said that at the point of measurement the qubit falls out of superposition. That implies to me that it would constantly have to fall in and out of superposition whenever it's changed inside a computer. Because if you want to know what information a qubit is carrying, you have to measure it, and to change it in a meaningful way, you have to know what information it has. Unless you knew the exact states and outcomes from the beginning, but that makes the whole process useless and doable with conventional computers.

                                                                          This would mean that the superposition property, which is the main (only?) advantage of quantum computing is ultimately useless.
