Simple Chemical Tweak Opens Practical Path to Topological Quantum Computing
Researchers have discovered that subtly adjusting the ratio of tellurium and selenium in ultra-thin films can trigger a topological superconducting state critical for stable quantum computers. The breakthrough offers a more practical manufacturing route for next-generation quantum devices.
- Adjusting the tellurium-selenium ratio in thin films triggers a topological superconducting state
- Topological superconductors host Majorana fermions — key building blocks for fault-tolerant quantum computers
- The method uses established thin-film growth techniques compatible with semiconductor manufacturing
- Could dramatically reduce the error-correction overhead that limits current quantum computers
