Title: JOSEPHSON TRANSMISSION LINE FOR SUPERCONDUCTING DEVICES
Abstract:
Josephson transmission lines (JTLs) for superconducting devices and related methods are provided. In one example, a device comprising a JTL for propagating quantum pulses in a first direction in response to an application of a clock signal having a plurality of phases is provided. The JTL may include a first inductive element coupled between a first terminal and a second terminal, a first Josephson junction (JJ) coupled between the second terminal and a ground terminal, a second inductive element coupled between the second terminal and a third terminal, and a second JJ coupled between the third terminal and the ground terminal. The second inductive element is configured to form an inductive loop, and the inductive loop may be configured to operate in a mode such that a quantum pulse cannot travel in a second direction opposite from the first direction regardless of a phase of the clock signal.
