The Defense Advanced Research Projects Agency (DARPA) has recently announced a groundbreaking program that aims to explore innovative methods of cooling superconducting electronic devices used in quantum computing. The Synthetic Quantum Nanostructures (SynQuaNon) program seeks to harness the potential of quantum heterostructures and other manmade metamaterials to regulate the temperature of these devices.
One of the major challenges in quantum computing is the need to maintain the devices at extremely low temperatures, typically just a fraction of a degree above absolute zero (-460 degrees Fahrenheit). Achieving such low temperatures traditionally requires large, power-consuming refrigeration units.
The SynQuaNon program aims to develop scalable prototypes that utilize energy-efficient, synthetic nano patterned structures to effectively manage the temperature of superconducting nanoelectronic devices used in quantum computing. By increasing the operating temperature of these devices by a factor of 10, the size of cooling refrigerators can be reduced by more than 100 times.
Mukund Vengalattore, the program manager at the Defense Sciences Office, explains the significance of reducing the power and cooling overhead required for quantum devices. “By reducing the size, weight, and power requirements, we can significantly improve the overall performance of these devices,” he said.
