    Abstract: The resonant conditions of non-linear Josephson junctions are reduced by shaping the junctions differently than a conventional rectangular shape. For a given value of L/ lambda J, where L is the junction length and lambda J is the Josephson penetration depth, non-rectangular junctions have reduced resonance current amplitudes when compared with rectangular junctions. The reduction in resonance current amplitudes allows the junction to be used in logic configurations with less stringent requirements on the current swings of the Josephson current required to perform switching.

    Abstract translation: 通过与传统的矩形形状不同地形成结，减少了非线性约瑟夫逊结的共振条件。 对于L /λJ的给定值，其中L是结长，λJ是约瑟夫逊渗透深度，当与矩形结相比时，非矩形结结具有降低的谐振电流幅度。 谐振电流幅度的降低允许结点用于对执行切换所需的约瑟夫逊电流的电流摆幅要求较低的逻辑配置。

    Abstract: Superconductive circuitry using a first Josephson tunneling device connected to a transmission line having a termination such that no reflections result when the Josephson tunneling diode switches between two stable voltage states, in accordance with applied input signals. Means are provided for producing the input signals to switch the first Josephson tunneling device and further Josephson tunneling devices are provided whose voltage state depends on the current pulse delivered to the transmission line when the first Josephson tunneling device switches from a first voltage state to a second voltage state. Logic circuitry is shown using this structure, as well as fan-in and fan-out Josephson tunneling device circuits.
