You can program the arduino to behave like this mythical IC
I'm not sure I really believe that we as a species understand quantum physics yet.
Given unlimited resources, a classical computer can simulate an arbitrary quantum algorithm so quantum computation does not violate the Church-Turing thesis. However, in practice infinite resources are never available and the computational basis of 500 qubits, for example, would already be too large to be represented on a classical computer because it would require 2500 complex values to be stored. Nielsen and Chuang point out that "Trying to store all these complex numbers would not be possible on any conceivable classical computer."
