摘要： One example includes a superconducting transmission line driver system. The system includes an input stage configured to receive an input pulse and an AC bias current source configured to provide an AC bias current. The system also includes an amplifier coupled to the input stage and configured to generate a plurality of sequential SFQ pulses based on the input pulse in response to the AC bias current. The system further includes a low-pass filter configured to filter the plurality of sequential SFQ pulses to generate an amplified output pulse that is output to a transmission line.

摘要： One example includes a superconducting clock conditioning system. The system includes a plurality of inductive stages. Each of the plurality of inductive stages includes an inductive signal path that includes at least one inductor and a Josephson junction. The superconducting clock conditioning system is configured to receive an input AC clock signal and to output a conditioned AC clock signal having an approximately square-wave characteristic and having a peak amplitude that is less than a peak amplitude of the input AC clock signal.

摘要： One example includes a superconducting transmission driver system. The system includes a latching gate stage comprising at least one Josephson junction configured to switch from an off state to an oscillating voltage state to provide an oscillating voltage at a control node in response to a single flux quantum (SFQ) pulse received at an input. The system further includes a low-pass filter stage coupled to the control node and configured to convert the oscillating voltage to a pulse signal to be transmitted over a transmission line.

摘要： A method for determining the phase noise of a fiber optic cable includes a step of transmitting a reference signal and a test signal over the fiber optic cable to be tested. The reference and test signal are provided with different wavelengths. The phase noise of the fiber optic cable is calculated by comparing the reference signal and the test signal output from the fiber optic cable.
