Shamiul Alam, Ahmedullah Aziz

Abstract: Ferroelectric Superconducting Quantum Interference Devices (Fe-SQUIDs) have recently gained attention as a transformative technology for superconducting computing, offering voltage-controlled switching that is essential for large-scale digital circuits. This unique technology has the potential to drive advancements in cryogenic computing by enabling scalable memory systems and voltage-controlled logic circuits. These innovations are critical for the realization of large-scale quantum computers and hold significant promise for high-performance computing and space exploration. In this article, we explore how Fe-SQUIDs, integrated with heater cryotrons (hTrons), can be harnessed to develop key components of computing systems. These include non-volatile memory, voltage-controlled logic circuits, in-memory matrix-vector multiplication systems, and ternary content-addressable memory. We also examine how changes in the key characteristics of Fe-SQUIDs and hTrons influence the performance of these applications, providing insights into the design and optimization of next-generation superconducting hardware.
