Yes, I confused the terms. However, my point remains valid. The article
was about quantum computing, and demonstrates that quantum computing
is still primitive. IMO quantum electronics is also still primitive,
which was the point of departure for the rest of my message, which
argued that nanoelectronics is harder than nanomechanics. Basically
quantum electronics is necessary for both nanoelectronics and
quantum computing, but is not sufficient for quantum computing.
