2026年のQ2B東京で皆様をお迎えできることを嬉しく思います！

As quantum hardware teams race toward fault tolerance, a critical bottleneck has emerged: designing and validating the architecture that turns thousands of noisy physical qubits into reliable logical ones. Plaquette is an industry-grade design-automation software platform that gives hardware teams instant access to a comprehensive library of quantum error-correction codes, state-of-the-art decoders, and a suite of proprietary simulators capable of capturing 20+ realistic error sources: including leakage, mode heating, and coherent errors, across superconducting, trapped-ion, neutral-atom, spin, and photonic platforms. Plaquette enables rapid architecture exploration and optimization, helping teams identify paths to commercially relevant fault tolerance years sooner than in-house approaches.

Quantum computing will not merely break encryption—it will redefine digital trust. The real challenge is not adopting post-quantum algorithms, but engineering confidence across the entire communication stack—from photonic links and QKD systems to AI-native cloud and 6G infrastructures. This talk challenges the industry to move beyond compliance-driven migration and toward performance-validated quantum resilience. We will explore how PQC, QKD, and hybrid architectures can be continuously tested, measured, and optimized at scale—transforming quantum risk into a competitive advantage.

This case study presents the development and active implementation of a post-quantum cryptographic (PQC) migration framework tailored for healthcare networks and industrial IoT environments. Grounded in over two decades of applied research in lattice-based cryptography and IoT security architecture, the framework addresses real-world engineering challenges in migrating constrained operational systems to NIST-finalized standards like ML-KEM (FIPS 203) and ML-DSA (FIPS 204). Healthcare and industrial IoT were identified as urgent-priority sectors due to their long data retention obligations and extended device deployment lifetimes, making them acutely vulnerable to harvest-now-decrypt-later threats. The framework adopts a crypto-agile, phased migration methodology incorporating hybrid ML-KEM/ECDH constructions, post-quantum authenticated boot chains for edge nodes, and a structured cryptographic surface audit process. The underlying research has accumulated over 5,000 citations, with active institutional engagement underway across the region.

光量子コンピュータは、他のハードウェア方式にはない特有の利点を有しており、近年異色のアプローチで躍進している。日本国内でも、プロトタイプマシンの開発や関連スタートアップの設立も進展し、注目を集めている。本講演では、光量子コンピュータの原理や研究動向、さらにその大規模化を目指して我々が独自に開発を進めている「ループ型光量子コンピュータ」について紹介する。

JHPC-quantumプロジェクトでは、ユーティリティスケールの量子HPCハイブリッド計算を目指して、IBMの超伝導量子コンピュータ「ibm_kobe」とQuantinuumのイオントラップ量子コンピュータ「黎明」をオンプレで導入し、これらの量子コンピュータを富岳をはじめとするスーパーコンピュータと結合して利用するJHPC-quantumプラットフォームを構築した。このプラットフォームを利用して、量子化学分野のアプリケーションでは実用に迫る成果がでており、外部ユーザーによる利用・評価を目的としたテストユーザープログラムではすでに21プロジェクトを実施中である。

In the JHPC-quantum project, we aim to realize utility-scale quantum–HPC hybrid computing by deploying on-premises quantum computers, IBM’s superconducting quantum computer “ibm_kobe” and Quantinuum’s trapped-ion quantum computer “Reimei.” We have built the JHPC-quantum platform, which enables these quantum systems to be integrated with supercomputers such as Fugaku. Using this platform, we have achieved results approaching practical applicability in quantum chemistry applications, and the Test User Program (TUP), designed for external users to evaluate and utilize the platform, is already underway, with 21 projects currently in progress.
