Quantum does not refer to small size, but to a quantized nature. In quantum physics, the energy level of an electron changes from one state or another without ever being at an intermediate level. It is quantized.

So a 'quantum leap' in technology is a sudden jump from one level to a much higher level which skips over the usual intermediate states - just like the leap of an electron to the next energy level.
