The company says that it used a-axis YBCO thin film material to generate a trilayer Josephson Junction (JJ) device. This type of a-axis YBCO superconducting material, says the company, when designed into JJ devices, enables simpler foundry fabrication, quantum device design, and high-performance analog and digital circuit solutions.
"These test results demonstrate that our proprietary technology of a-axis YBCO material is not only extremely high-quality, it can be designed into JJ devices," says Ron Kelly, Ambature CEO. "This allows us to accelerate our plans to scale this technology in stand-alone JJ applications or in volume with traditional silicon foundries."
JJ's have been shown to be a perfect vehicle for high-performance and energy-efficient products, says the company, and its test results demonstrate a huge step forward for the industry. The potential for increased performance in applications include high-performance and quantum computing, autonomous vehicles, telecommunications, data centers, medical diagnostics and AI. These applications have multiple use cases for both commercial and military markets.
The test results follow the company's success in generating very high-quality a-axis YBCO material . The use of a-axis architecture YBCO, says the company, as opposed to the common approach of using conventional c-axis architecture with other materials, allows easier fabrication of JJ devices in large-scale foundries.
The company says its JJ technology enables an extremely fast and energy-efficient computer processor and one of the best sensors in the entire electromagnetic spectrum. Its core JJ technology addresses two basic problems: parasitic heat and short-lived quantum coherence.
Parasitic heat is caused by electrical resistance in devices such as computers, cell phone base stations, data centers and batteries. It is the major barrier to advances in semiconductor power, speed, efficiency, density and reliability. Short-lived quantum coherence is a barrier to advances in a number of applications exploiting quantum effects - most notably quantum computers.
The semiconductor industry needs new materials, architectures, and circuit designs to address these problems, says the company,
