    Abstract: A high frequency parametric amplifier using the quantum mechanical oscillation associated with transitions of electron pairs between two macroscopic quantum states, (Josephson tunneling) as the source of the idler or pumping frequency. An incoming signal causes the relative phase of two such cross coupled quantum amplifiers to change. This produces a change in the low frequency resistance of the device leading to relatively large output voltages.

    Abstract: A neuristor transmission line is disclosed, capable of propagating a pulse without substantial attenuation, and comprising a pair of elongated closely spaced line conductors made of superconductive materials, and a thin barrier layer of non-superconductive material disposed between said line conductors, said layer being sufficiently thin to be readily penetrable by tunneling electrons. A learning junction is also disclosed, adapted to be connected between neuristor transmission lines, and comprising a pair of superconductive elements, and an intermediate element of saturable ferromagnetic material disposed between said superconductive elements. Also disclosed is an array of artificial neurons, comprising a plurality of neuristor transmission lines as described above, and a plurality of learning junctions connected between at least some of said neuristor transmission lines.
