I don't know how she could say this with any authority. One of the biggest roadblocks in quantum computing is finding a faster way to make quantum logic gates. So far they're only making them one by one, when tens of thousands are needed. We will not be using this tech anytime soon.

Using subattomic computers to learn about subattomic particles. That will lead to better subattomic computers which will lead to... (A virtuous cycle like Moore's Law?)

It was nice to see this comment, because to me it means that she is always looking to the future & optimistic.

One of the near-term applications of quantum computing is for machine learning. For example, the D-wave chip is for optimising a binary fitness function. We will soon see if it works out.
