Is that different than a regular computer? To take your statement and slightly modify it: some sort of device to set electromagnetic charges, then run an "electromagnetic algorithm" (i.e. a graph of "electromagnetic logic gates"), and finally read out the "sequence of electromagnetic bits" resulting from the algorithm. That sounds to me like the computer that I am typing on now. Am I missing something here?
