You have 127 qubits that you measure and you end up with a classical string of length 127. Sure, that classical string, the measurement result, could have ended being any of 2^127 possible different values into which the wavefunction collapses. But that is no different from saying that there are 1^1024 possible states that a 1kB of classical RAM can be in. It is not related to the (conjectured) computational advantage that quantum computers have.

Right okay makes sense...guess I am just too used to NISQ and having to run many thousands of shots for high enough fidelity..if all you wanted was one output, then yeah one classical string is easy enough, thanks
