• This article describes simulation study on SQUID applications for Single-Flux-Quantum(SFQ) Logic Circuits. Here, a SQUID is compatible to a Quantum Flux Parametorn (QFP) [3], [4]. Several new circuits based on a SQUID are investigated. A cascaded SQUID is proposed with the signal amplitude in the same order of an SEQ. An SFQ-pulse driving circuits with the new SQUID are success- fully simulated. An SFQ trap which catches SEQs is newly proposed. Focusing on a circulating current of a segment in a Josephson transmission line (JTL), an SEQ-pulse is non-destructively detected by a SQUID. A conventional SQUID inserted in a JTL operates as a gate which controls SEQ-pulse transmission through it. Compatibility of SQUIDs and SEQ circuits is demonstrated
