SUMMARY:Toward constructing a large-scale quantum computer based on TQFT
DESCRIPTION:Quantum Field Theory and Physical Mathematics Seminar \nSpeaker: Liyuan Chen ( Harvard) \nTitle: Toward constructing a large-scale quantum computer based on TQFT \nAbstract: Topological quantum computation\, motivated by topological quantum field theory (TQFT)\, offers a promising path toward fault-tolerant universal quantum computation. However\, the practical realization of such a system remains challenging due to the difficulty of finding suitable topological materials. In this work\, we provide a comprehensive blueprint for constructing a fault-tolerant universal quantum computer based on the quantum double model $\mathcal{D}(S_3)$\, a specific non-Abelian topological order. We implement logical computations using quantum circuits on qubits and qutrits\, including a single non-Clifford gate\, compatible with near-term quantum devices. This work bridges the gap between abstract mathematical frameworks and noise-resilient quantum computation on near-term devices. Our proposal offers a promising path to realize a non-Abelian anyon-based large scale quantum computer.
