    摘要: One example includes a superconducting circuit. The circuit includes a plurality of layers comprising a first conductor layer and a second conductor layer overlying the first conductor layer, each of the first and second conductor layers comprising at least one signal element. The circuit also includes a ground grid that is conductively coupled to ground and comprises a first plurality of parallel ground lines that occupy the first conductor layer and extend in a first direction and a second plurality of parallel ground lines that occupy the second conductor layer and extend in a second direction that is orthogonal with respect to the first direction.

    摘要: One embodiment describes a quantum memory system. The system includes a plurality of quantum memory cells arranged in an array of rows and columns. Each of the plurality of quantum memory cells can be configured to store a binary logic state in response to write currents in a write operation and configured to provide an indication of the binary logic state in response to read currents in a read operation. The system also includes an array controller comprising a plurality of flux pumps configured to provide the write currents and the read currents with respect to the rows and columns. The array controller can be configured to control timing associated with the write operation and the read operation in response to memory request signals based on application of the write currents and the read currents and based on recharging flux associated with the plurality of flux pumps.

    摘要: One embodiment describes a reciprocal quantum logic (RQL) receiver system. The RQL system is configured to convert a serial input data stream provided from a serial data transmitter into an RQL data stream. The RQL receiver system includes a sampling controller configured to oversample the serial input data stream via a plurality of samples over each sampling window of an RQL clock signal to determine a transition sample corresponding to a transition in a digital value of the serial input data stream in a given one sampling window of the RQL clock signal. The RQL receiver system can be further configured to capture the digital value of the serial input data stream via a capture sample that is a predetermined number of samples subsequent to the transition sample in each sampling window of the RQL clock signal.
