Applied and Computational Math Seminar [url]
Non-Abelian magic in quantum error correction
- Yanzhu Chen, Physics
Time: 3:05pm Room: LOV 231
Abstract/Desc: Quantum computing has the potential to enable capabilities beyond those of classical computing, yet quantum information itself is inherently fragile and highly susceptible to errors. Quantum error correction technologies have thus been developed to provide fault tolerance in computation. In universal fault‑tolerant quantum computing, logical non‑Clifford gates are essential, but their realization often requires substantial spacetime overhead in many error‑correcting codes, including the high‑threshold surface code. In this talk, I will first introduce the idea of quantum error correction, stabilizer codes, and universal quantum computing. Then I will provide an overview of our recent work on two strategies of implementing logical non-Clifford operations in the surface code with the aid of non-Abelian topological order, which bypass the need for the resource-intensive distillation procedure. The first method produces a logical magic state through transformations of topological codes. In the second approach we generalize the standard lattice surgery to hybrid lattice surgery across different topological codes.
