A Revolutionary Finding
Joe Carroll, the lead author and a PhD researcher working with UCC Prof. Séamus Davis, describes the subject of the paper.
“Superconductors are remarkable materials possessing strange and rare attributes. Most notably, they enable electric current to flow without any resistance, meaning they don’t heat up, and in fact, don’t waste any energy despite carrying substantial current. They achieve this because electrons move in pairs instead of individually through the metal, forming a macroscopic quantum mechanical fluid.”
“Our team uncovered that some electron pairs establish a new crystal structure within this background fluid. First identified by our group in 2016, these states are now referred to as Electron Pair-Density Waves. We are still exploring the characteristics of these Pair Density Waves, a novel form of superconducting matter.”
“The excitement for us and others in the field is that UTe2 appears to be a unique type of superconductor. It’s a material that physicists have sought for nearly four decades. If the observed intrinsic angular momentum in electron pairs is confirmed, we have detected the first Pair-Density Wave made of these rare electron pairs.”
Quantum Computing’s Real-World Consequences
When questioned about the tangible implications of this research, Mr. Carroll elucidated:
“Evidence suggests that UTe2 is a special superconductor that might have vast implications for quantum computing.”
“In contrast to classical computers that use bits, quantum computers employ quantum bits or qubits. The current problem with quantum computers is the delicate superposition of qubits that can easily collapse, cutting off computation. This presents a significant limitation to quantum computers’ application.”
“However, the last five years of research on UTe2 point towards it being a superconductor suitable for topological quantum computing. This approach can eliminate the limitations on qubit lifetime during computation, enabling more stable and practical quantum computers. Microsoft has already invested heavily in this area, underlining its established theoretical foundation.”
“The search has been on for a relevant topological superconductor, and UTe2 appears to fit the bill. Our discovery adds another dimension to the understanding of UTe2 and brings us closer to more feasible quantum computers.”
Conclusion and What Lies Ahead
Congratulating the team at University College Cork’s Macroscopic Quantum Matter Group Laboratory, Professor John F. Cryan, Vice President Research and Innovation, stated:
“This vital discovery will play a major role in the future of quantum computing. In the coming weeks, the University will unveil UCC Futures – Future Quantum and Photonics, and the research led by Professor Seamus Davis and his team, aided by one of the world’s most powerful microscopes, will be central to this thrilling initiative.”
