Tailoring quantum oscillations of a Bose-Einstein condensate of excitons as qubits

What plagues quantum upscaling? Most quantum computing devices are dependent on using complex physical phenomena that are either very short-lived (~10-12 seconds) and/or only survive at ultra-low temperatures (e.g., 10-3 ...
