We're excited to host you all at Q2B Tokyo in 2026!

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.

Photonic quantum computers possess unique advantages not found in other hardware platforms and have made remarkable progress in recent years through unconventional strategies. In Japan as well, significant advances have been achieved, including the development of prototype machines and the establishment of related startups, drawing considerable attention. In this talk, I will introduce the principles and current research trends of photonic quantum computing, as well as our original “loop-based photonic quantum computer” towards large-scale implementation.

This presentation delves into the evolving landscape of quantum technology, examining its transformative potential and the challenges that lie ahead. It provides a comprehensive overview of recent breakthroughs, real-world applications, and their implications across various industries. Additionally, it explores emerging research directions and future prospects, shedding light on the trajectory of this rapidly advancing field.

Deloitte Tohmatsu’s quantum projects bring together a diverse team of experts, including researchers and consultants from various industries, to seamlessly drive initiatives ranging from use case development and ecosystem building to business creation support. In this session, we will share the results of our research in areas such as drug discovery and materials development, as well as discuss key actions companies should take to create new quantum businesses.

This presentation will go over some of the 2025 and 2026 activity in terms of market trends in the quantum sector, we will explore use-cases for quantum technologies spanning sensing, comms and computing, as well as hardware roadmaps and geopolitical driving forces that accelerate or slow adoption of quantum in industry verticals.
