Ferroelectric SQUID logic: voltage-controlled Boolean circuits for cryogenic and quantum computing
Voltage-controlled Boolean logic gates built on a ferroelectric SQUID (FeSQUID) enable logic and memory to be implemented with the same device, minimizing mismatch in speed, power consumption, and fabrication process.
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.
Benefits
- Allows for smaller physical distance between components for improved computing power, weight reduction, and space saving.
- Combined memory technology that can operate under 4 Kelvin, allowing for use in space tech, quantum computing and superconducting electronic platforms.
- Scalable technology.
Patent status
