I think their universal quantum computer (to be announced later this year) could accelerate fusion research even more, as I imagine it could more accurately simulate the atom reactions and experiments on it. Practical quantum computers may just be what we were missing to finally be able build working fusion reactors.
The millions of possible "solutions" and algorithms for working fusion reactors may be what has made fusion research so expensive and fusion reactors seem so far away. Quantum computers may be able to cut right through that hard problem, although we may have to wait a bit more until quantum computers are useful enough to make an impact on fusion research. I don't know if that's reaching 1,000 qubits or 1 million qubits.
