Research summary
Quantum computing has the potential to change the world, but there’s a challenge: these powerful computers are easily disturbed by their surroundings. This is known as the decoherence problem. One way to reduce decoherence is to use special states within certain types of superconductors (materials that can conduct electric current with no resistance below a certain critical temperature). But until recently, these have tended to work only at very low temperatures. Now, a theory has emerged about a new type of structure—called a twisted cuprate structure—that has the potential to perform as a superconductor at higher temperatures.
As Canada Research Chair in Two-dimensional Quantum Materials, Dr. Ziliang Ye plans to create and study these structures to see if they can maintain these special states at higher temperatures. If he and his research team succeed, the results could be a game-changer for quantum computing and make these powerful computers more practical and accessible.
