The order parameter of a superconductor is reduced by Injecting spin-polarized carriers into the superconductor. The reduction in the order parameter is used to modulate the critical current of the superconductor In a typical embodiment a current is caused to flow through a superconductor. Spin polarized electrons are then injected into the path of the current in the superconductor by biasing a magnetic metal with respect to a terminal of the superconduction the bias current may be varied to modulate the injection and thus the flow of current through the superconduction
