Scientists at the University of Chicago and West Virginia University have found a way to create topological superconductors, which are crucial for next-generation quantum computers. They did this by slightly adjusting a chemical formula.

Quantum computers are much faster than regular computers when it comes to complex tasks like discovering new medicines or breaking encryption codes. However, they need rare materials called topological superconductors that are hard to create and control. Researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) and West Virginia University have now found a way to make these materials more accessible.

They focused on ultra-thin films made from two elements, tellurium and selenium. By carefully changing the proportion of these elements, they discovered that they could push the material into different quantum phases, including the topological superconductor phase.

Their results show that by slightly adjusting the chemical formula, scientists can control how strongly electrons interact with each other. This is like a fine-tuning mechanism that allows them to deliberately engineer unusual quantum states.

"We can tune this correlation effect like a dial," said Haoran Lin, a UChicago PME graduate student and first author of the new work. "If the correlations are too strong, electrons get frozen in place. If they're too weak, the material loses its special topological properties. But at just the right level, you get a topological superconductor."
