Constant-rate quantum codes with low-weight stabilizers and full logical Clifford actions via transversal and fold-transversal gates
Takaya Matsuura, Yohji Chin, Shohei Kiryu +1
Low-space-overhead fault-tolerant quantum computation requires not only high-rate quantum error-correcting codes but also space-efficient implementations of logical operations. Tra…
Fundamental limits of parameter estimation with heralded optical non-Gaussian states generated from Gaussian resources
Shohei Kiryu, Kazufumi Tanji, Yoshihiro Ueda +2
Non-Gaussian states can exhibit large quantum Fisher information (QFI) in quantum sensing. In optical systems, however, its generation is often probabilistic via the boson-sampling…
All-optical Implementation of Generalized Quantum Teleportation
Takaya Hoshi, Akito Kawasaki, Xiruo Yan +7
Measurement-based continuous-variable optical quantum computing inherently offers high-speed, large-scale operations, yet its practical performance remains constrained by the proce…
Linear-optical generation of hybrid GKP entanglement from small-amplitude cat states
Shohei Kiryu, Yohji Chin, Masahiro Takeoka +1
Hybrid bosonic codes combining bosonic codes with photon states offer a promising pathway for fault-tolerant quantum computation. However, the efficient generation of such states i…
Beyond Stellar Rank: Control Parameters for Scalable Optical Non-Gaussian State Generation
Fumiya Hanamura, Kan Takase, Hironari Nagayoshi +6
Advanced quantum technologies rely on non-Gaussian states of light, essential for universal quantum computation, fault-tolerant error correction, and quantum sensing. Their practic…
Linear optical quantum computing with a hybrid squeezed cat code
Shohei Kiryu, Kosuke Fukui, Atsushi Okamoto +1
In recent years, squeezed cat codes with resilience to specific types of loss have been proposed as a step toward realizing fault-tolerant optical quantum computers. However, error…
