Voltage-Controlled Boolean Logic Circuit Based on Ferroelectric SQUID
The Problem
Superconducting devices have been introduced for cryogenic logic gates to fit the increased demand in quantum computing and space exploration. Introducing voltage gating to these devices has been difficult, and these devices cannot be used like semiconducting transistors to design logic gates.
The Solution
Researchers at the University of Tennessee have designed unique voltage-controlled Boolean logic gates utilizing ferroelectric SQUID (FeSQUID). The FeSQUID-based memory technology enables the implementation of an entire system using the same device and will ensure minimum mismatch between logic and memory in terms of speed, power consumption, and fabrication process. This technology has a revolutionary potential within the field of quantum computing and supercomputing electronics.
