SuperConga: The game-changing software accelerating quantum research

GOTHENBURG, Sweden — In the near future, quantum technology is set to revolutionize society, impacting areas like healthcare, communication, defense, and energy.  Of particular interest are the superconducting properties, which enable perfect conductivity and unique magnetic characteristics in quantum components. These properties have already led to innovations like magnetic resonance imaging and quantum computer components.

Researchers believe that there are countless untapped quantum properties and applications yet to be explored. At Chalmers University of Technology in Sweden, a team of researchers has developed open-source software called SuperConga, which is freely available to accelerate quantum research and unlock new breakthroughs.

How does SuperConga work?

SuperConga operates at the mesoscopic level, allowing simulations that capture the peculiar behavior of quantum particles and apply them practically. This pioneering code is the world’s first of its kind and is expected to uncover novel superconducting properties, paving the way for quantum computers capable of addressing societal challenges across various domains.

Unconventional superconductors, in particular, are a mysterious field, and understanding their properties is crucial for advancing quantum computing. The Chalmers team aims to unlock their secrets and uncover new applications using SuperConga. The software is user-friendly, powerful, and educational, designed to facilitate new understandings and drive innovation in unexplored areas of superconductivity.

“We want to find out about all the other exciting properties of unconventional superconductors. Our software is powerful, educational and user-friendly, and we hope that it will help generate new understanding and suggest entirely new applications for these unexplored superconductors,” says Patric Holmvall, postdoctoral researcher in condensed matter physics at Uppsala University, in a statement.

The researchers at Chalmers want to simplify the lives of quantum researchers and students by providing the necessary tools to study and utilize quantum properties effectively. Working at the mesoscopic scale, which bridges the microscopic and macroscopic worlds, they aim to bridge the gap between theoretical potential and practical implementation.

“Extremely simplified models based on either the microscopic or macroscopic scale are often used at present. This means that they do not manage to identify all the important physics or that they cannot be used in practice,” says Tomas Löfwander, Professor of Applied Quantum Physics at Chalmers. “With this free software, we want to make it easier for others to accelerate and improve their quantum research without having to reinvent the wheel every time.”

The study is published in the journal Applied Physics Reviews.

  1. I would add Stallion Gate by Martin Cruz Smith! Considering all the hoopla about Oppenheimer, this novel brings to life the the events as see through the Native American army sergeant who is Oppie’s jeep driver,. With the added dimension of the Native American nature sensibilities infused throughout. I loved it.
