Quantum states are incredibly fragile and can be disturbed with even the slightest interaction with the environment (called decoherence). These devices are cooled and isolated to the most extreme degrees possible and still at present decoherence severely limits the computations that can be performed.
I think with all the footage of Trump, and his shallow personality, an AI will be trained to impersonate him and we’ll never be rid of him. I’m sure techbros are working on their animatronic Trump right now.
