I'm well aware. I'm also aware that the various levels of error correction in a typical computer manage to retain the data integrity potentially for years or even decades.

Google bragging about an hour, regardless of it being a different type of computer, just sounds pathetic, especially given all the money being invested in the technology.

Traditional bits only have to be 0 or 1. Not a coherent superposition.

Managing to maintain a stable qubit for a meaningful amount of time is an important step. The final output from quantum computation is likely going to end up being traditional bits, stored traditionally, but superpositions allow qubits to be much more powerful during computation.

Being able to maintain a cached superposition seems like it would be an important step.

(Note: I am not even a quantum computer novice.)
