基于快速单通量量子（RSFQ）技术设计并仿真了双轨逻辑电路元件。所提出的电路可以异步操作，因为双轨数据本身包括定时信息。因此，双轨逻辑方案有可能解决流时钟RSFQ电路的一些问题，这些问题随着电路的操作速度和复杂度的增加而变得更加严重。描述了RSFQ双轨AND和XOR单元的实现。本文还提出了一种从流时钟电路向并行双轨电路传输环路数据的方案，即一种全异步双轨解复用器。
Dual-rail logic circuit elements based on rapid single-flux-quantum (RSFQ) technology have been designed and simulated. The proposed circuits can operate asynchronously, since dual-rail data include timing information in themselves. Therefore dual-rail logic scheme has a possibility of solving some problems of RSFQ circuits with flow clocking, which would become more serious as operating speed and complexity of the circuit increase. Implementation of RSFQ dual-rail AND and XOR cells is described. A scheme of transfer-ring data from a flow-clocked circuit to a parallel dual-rail circuit is also proposed, which a fully asynchronous dual-rail demultiplexer.
