# Quantum computer “scaling”?

Hello,

Is this true generally? for only a subset of problems? at all? If for only a subset, does it apply to grover’s algorithm, and theoretically if one could scale a quantum computer to a very large number of qubits, say a million/billion ( analogous to say the growth in the semiconductor industry ) could you use it to search for the correct solution in a fairly reasonable amount of time to a problem of a similar size to the number of qubits?

Any help will be apprecited.

I didn’t find the right solution from the Internet.
