It hard to know if that theory is going to translate into reality. The machinery required for isolating the qubits, configuring the qubits for a computation, and reading out the qubits at the end may prevent very much scaling.

Science fiction has hypothesized about quantum computing that involves macroscopically-sized bits of carefully constructed matter running a number of qubits best described with scientific notation, but it's not clear how one would set up problems or read anything out of such a thing.
