Doubly-polylog-time-overhead fault-tolerant quantum computation by a polylog-time parallel minimum-weight perfect matching decoder
Yugo Takada, Hayata Yamasaki
Reducing space and time overheads of fault-tolerant quantum computation (FTQC) has been receiving increasing attention as it is crucial for the development of quantum computers and…

Efficient Magic State Distillation by Zero-Level Distillation
Tomohiro Itogawa, Yugo Takada, Yutaka Hirano +1
Magic state distillation (MSD) is an essential element for universal fault-tolerant quantum computing, which distills a high-fidelity magic state from noisy magic states using idea…

Clifford gates with logical transversality for self-dual CSS codes
Theerapat Tansuwannont, Yugo Takada, Keisuke Fujii
Quantum error-correcting codes with high encoding rate are good candidates for large-scale quantum computers as they use physical qubits more efficiently than codes of the same dis…
