Loss-correcting fault-tolerant quantum computing architecture for neutral atoms
Sanaa Sharma, Yutaka Hirano, Akihisa Goban +3
Neutral-atom arrays are a leading qubit technology for large-scale, fault-tolerant quantum computing (FTQC). A dominant error source on this platform is qubit loss, which accrues w…
Zero-level Distillation
Tomohiro Itogawa, Yutaka Hirano, Yutaro Akahoshi +1
Magic state distillation is a key component of fault-tolerant quantum computation, as it enables the implementation of non-Clifford gates such as the gate and the gate vi…
Entanglement boosting: Low-volume logical Bell pair preparation for distributed fault-tolerant quantum computation
Shinichi Sunami, Yutaka Hirano, Toshihide Hinokuma +1
Distributed architecture is a promising route to scaling fault-tolerant quantum computing (FTQC) beyond the inherent limitations of single processors. For practical implementation…
Efficient magic state cultivation with lattice surgery
Yutaka Hirano, Riki Toshio, Tomohiro Itogawa +1
Magic state distillation plays a crucial role in fault-tolerant quantum computation and represents a major bottleneck. In contrast to traditional logical-level distillation, physic…
Measurement-Based Fault-Tolerant Quantum Computation on High-Connectivity Devices: A Resource-Efficient Approach toward Early FTQC
Yohei Ibe, Yutaka Hirano, Yasuo Ozu +2
We propose a measurement-based FTQC (MB-FTQC) architecture for high-connectivity platforms such as trapped ions and neutral atoms. The key idea is to use verified logical ancillas…
Locality-aware Pauli-based computation for local magic state preparation
Yutaka Hirano, Keisuke Fujii
Magic state distillation, a process for preparing magic states needed to implement non-Clifford gates fault-tolerantly, plays a crucial role in fault-tolerant quantum computation.…
