Quantum Sensing of Non-Repeatable Events Enhanced by In-Sensor Quantum Reservoir Computing
Daiki Sasaki, Hideaki Kawaguchi, Yuichiro Matsuzaki
High-density nitrogen-vacancy (NV) ensembles in diamond enable sensitive magnetometry. Many quantum-sensing protocols rely on reproducible target fields, allowing repeated measurem…
QuBridge: Layer-wise Fidelity Decomposition in Quantum Computation Pipeline
Kisho Sotokawa, Hideaki Kawaguchi, Shin Nishio +1
Running a quantum circuit on current hardware involves a sequence of engineering decisions, each with tunable parameters and distinct error characteristics. Existing tools optimize…
Digital Annealer-Assisted CNOT Oriented Quantum Circuit Transpilation with Integrated QUBO Mapping and Routing
Kazuma Watanabe, Hideaki Kawaguchi, Shin Nishio +1
Limited qubit counts and two-qubit gate errors motivate reducing CNOT overhead in noisy intermediate-scale quantum (NISQ) transpilation. In circuit-partitioning workflows, repeated…
Quantum-Enhanced Processing with Tensor-Network Frontends for Privacy-Aware Federated Medical Diagnosis
Hiroshi Yamauchi, Anders Peter Kragh Dalskov, Hideaki Kawaguchi +1
We propose a privacy-aware hybrid framework for federated medical image classification that combines tensor-network representation learning, MPC-secured aggregation, and post-aggre…
Practical Quantum Federated Learning for Privacy-Sensitive Healthcare: Communication Efficiency and Noise Resilience
Suzukaze Kamei, Hideaki Kawaguchi, Takahiko Satoh
AI-driven medical diagnostics increasingly requires collaborative model training across institutions, yet centralizing patient data conflicts with privacy regulations. Federated Le…
Telemetry-Based Server Selection in the Quantum Internet via Cross-Layer Runtime Estimation
Masaki Nagai, Hideaki Kawaguchi, Shin Nishio +1
The Quantum Internet will allow clients to delegate quantum workloads to remote servers over heterogeneous networks, but choosing the server that minimizes end-to-end execution tim…
