摘要： A reciprocal quantum logic (RQL) latch system is provided. The latch system comprises an output portion that retains a state of the latch system, and a bi-stable loop that comprises a set input, a reset input and an output coupled to the output portion. A positive single flux quantum (SFQ) pulse on the set input when the latch system is in a reset state results in providing a SFQ current in the output portion representative of the latch system being in a set state.

摘要： In one embodiment, the disclosure relates to a single flux quantum (SFQ) signal transmission line powered by an AC power source. The AC power source supplies power to a transformer having a primary winding and a secondary winding. The primary winding receives the AC signal and the secondary winding communicates the signal to the SFQ transmission line. The transmission line can optionally include an input filter circuit (125) for receiving the incoming SFQ pulse. The filter circuit can have a resistor (123) and an inductor (122) connected in parallel. A first Josephson junction (110) can be connected to the filter circuit and to the secondary winding. The Josephson junction triggers in response to the incoming SFQ pulse and regenerates a pulse signal in response to a power discharge from the secondary winding.

摘要： Superconducting single flux quantum circuits are disclosed herein, each having at least one Josephson junction which will flip when the current through it exceeds a critical current. Bias current for the Josephson junction is provided by a biasing transformer instead of a resistor. The lack of any bias resistors ensures that unwanted power dissipation is eliminated.

摘要： A second order superconductor delta-sigma analog-to-digital modulator having an input for receiving an analog signal, a first integrator coupled to the input, a second integrator cascaded with the first integrator, and a quantum comparator digitizing output from the second integrator reduces quantization noise by providing matched quantum accurate DACs in a feedback loop between output from the quantum comparator and input to the first integrator. The matched quantum accurate feedback DACs produce identically repeatable voltage pulses, may be configured for multi-bit output, may be time-interleaved to permit higher clocking rates, and may be employed in a balanced bipolar configuration to allow inductive input coupling. Bipolar feedback is balanced when gain of a first DAC exceeds gain of a matched, opposite polarity DAC by the amount of implicit feedback from the comparator into the second integrator.

摘要： one embodiment, the disclosure relates to a single-flux quantum logic gate capable of providing output from one of the two inputs, which is also known as the A and NOT B gate. The logic gate includes a first input gate and a second input gate for respectively receiving a first input pulse and a second input pulse. An output gate is wired in parallel with the first input gate. A first Josephson junction and a second Josephson junction are connected to the first input gate and the second input gate, respectively. A cross-coupled transformer is also provided. The cross-coupled transformer diverts the first pulse from the output gate if the second pulse is detected at the second input gate. In an optional embodiment, the first Josephson junction has a first critical current which is selected to be less than the critical current of the second Josephson junction.
