Most quantum computers need to be cooled to frigid temperatures or contained in space-like vacuum chambers. Using light to do the computation avoids both of those fates, but at a cost—how do you hold a light beam in your hand long enough to do the computation? There are many approaches, and now a team in Japan has created a light-based quantum machine that's capable of many different computations, and will be available on the cloud in 2025.
It’s been working for a number of years, just at small scales. Quantum computing has been a thing for a number of years now, just at very small scales. And as you’ve said, graphene has been around too! Just at very small scale.
I would say it’s almost exactly like fusion then.
