Zero clearing method and system for superconducting circuit

Abstract

The invention provides a zero clearing method and system for a superconducting circuit. The method comprises the following steps: sending a zero clearing instruction signal to an instruction input interface of a non-destructive read-out register, wherein the non-destructive reading register outputs data to a first magnetic flux quantum separation device according to the high-frequency local clocksignal, and the first magnetic flux quantum separation device separates the output data into a zero clearing signal and a trigger signal and inputs the zero clearing signal to a superconducting register between pipeline stages of the superconducting processor; inputting a low-frequency system clock signal to a second magnetic flux quantum separation device, wherein the second magnetic flux quantumseparation device splits the low-frequency system clock signal into a first low-frequency system clock pulse and a second low-frequency system clock pulse; the first D trigger outputs a signal pulseaccording to a trigger signal and a first low-frequency system clock pulse, the second magnetic flux quantum separation device outputs a delay pulse according to the signal pulse and a second low-frequency system clock pulse, and the non-destructive reading register resets according to the delay pulse so as to stop outputting a zero clearing signal.

The design of existing superconducting circuit components is mostly based on traveling wave and flowing water, without the traditional flip-flop concept, which makes it difficult to realize the register function

In the world, research and development institutions such as the United States and Japan have proposed to use limited units to build serial shift registers, but this type of register can only be read and written by serial shifting, and its performance is relatively low.

However, no specific design has been proposed for the zero-resetting signal g...
