Terahertz Technology Research with Potential to Accelerate Quantum Computing Development

( Little is understood about the quantum matter and quantum energy at terahertz and nanometer scales.
However, a new research into terahertz technology conducted by Iowa State University (ISU( shed some light on supercurrents and could lay the groundwork for its practical application in the field of quantum computers. Jigang Wang, professor of physics and astronomy at ISU, is studying how to control superconductivity beyond the gigahertz barrier, or the “bottleneck in the current state-of-the-art quantum computation applications.”
In his study supported by the Army Research Office, showed the potential of “light-Induced supercurrents” in the development of quantum computers. The team used terahertz light as a “control knob” to accelerate supercurrents. This terahertz technology could have several practical applications.
“Light-induced supercurrents chart a path forward for the electromagnetic design of emergent materials properties and collective coherent oscillations for quantum engineering applications,” Wang and team reported. “By exploiting interactions of these quantum systems, next-generation technologies for sensing, computing, modeling, and communicating will be more accurate and efficient.”
