The Problem Is How to Isolate Qubits From Their Environment
Theory of quantum error correction and quantum fault tolerance is what set the engineering agenda for quantum computing research from the 1990s until the present. The goal has been to engineer qubits that are not perfectly reliable, but reliable enough that you can then use these error correcting codes to have them simulate qu bits that are even more reliable than they are right now. And once you reach that sort of crossover point, then your qubits could in turn simulate qubits that were so much more reliable on their own. We're still a hell of a long way away from being able to do this with an arbitrary number of as many qubits as I want; it's going to take some time before we
