Spin-orbital quantum cellular automata logic devices and integrated circuits in the form of a substrate having a thin film of material on the substrate having strongly coupled spin-orbital states, the thin film being patterned to define at least one input and at least one output, and to perform at least one logic operation by associated arrangement of the spin-orbital states between the input and the output. The logic devices and integrated circuits further include an input device at each input to define the spin-orbital states at each input, and an output sensor at each output for sensing the spin-orbital states of the thin film at the output. In an integrated circuit, the output of one gate or circuit, in the form of the ferromagnetically aligned spins, can be directly coupled to the next gate or circuit, so that entire circuits can be fabricated and effectively interconnected, only requiring interfacing for overall. circuit input and output using the electromagnetic inputs and magnetic measurements for the outputs.
