But that is just hedging the bets - it does not show that the path to practical quantum computers at scale to handle real problems is feasible. We see customers getting requirement requests for using PQ safe crypto algorithms to be used in systems that will be used 30+ years. But that too is also just hedging the bets. Quantum Key Distribution is feasible - esp for systems that don't need to move and where you own the medium. And can spend the 1000+ kUSD these machines costs. For most use cases (for example between a client and a server setting up a secure session over Internet) these machines does not solve anything. But they sure are very cool to own and deploy.
