We're excited to host you all at Q2B Tokyo in 2025!

Realizing the full benefits of quantum computing requires the development of large-scale, fault-tolerant quantum computers, where photonics emerges as the most promising approach to accomplish this objective. One of the major hurdles in realizing large-scale photonic quantum computers lies in the generation of single photons and entangling gates. Quantum Source has developed a unique solution that significantly outperforms conventional methods in terms of efficiency, enabling the development of quantum computers with millions of qubits operating at room temperature.

Although quantum security technologies already can be applied for the long-term protection of valuable assets, current level of their implementation enables limited support for building quantum ready enterprise security systems. This presentation describes: + implementation of specific uses cases where we were able to successfully apply both QKD and PQC for securing data and processes. + integration of quantum security solutions into the enterprise infrastructure. + challenges we encountered along the road and how we addressed them. + rationale for the custom implementation of the hybrid of the key management system (KMS).

Diamond quantum technologies are differentiated by the diversity of their applications across sensing, computing and communications and potential to deliver miniaturized mass-deployable devices to mass markets. Over the last 5 years, there has been a dramatic growth of the diamond quantum industry and an acceleration of the technology. Key to the future of diamond quantum technologies is the development of the integrated diamond quantum chip, which is the core focus of Quantum Brilliance and a profound opportunity for Japan.

GQI has created an extensive data base consisting of hundreds of potential applications for quantum computing showing where this technology could be used. We have classified these use cases according to a number of different attributes including industry, problem area, algorithm, speedup potential, performance requirements, potential market size, etc. This presentation will provide a summary of our findings from this study.

Quantum clocks and sensors can provide highly precise timing and navigation in GPS-denied environments, but their widespread adoption is hindered by technical, economic, and policy bottlenecks. This presentation will examine strategies for governments to accelerate the development and deployment of quantum sensors to bolster national security applications in defense and critical infrastructure.

We will introduce low-noise DC power supplies, low-noise voltage/current sources, and low-noise amplifiers that support quantum computing. By utilizing analog circuit technologies, we have achieved excellent low noise performance.

Exploring the prospects and challenges of establishing an ecosystem for the creation of quantum market.

Quantum Extreme Learning Machines (QELMs) adapt classical extreme learning machines for quantum computing, offering faster training with fewer features and potentially improved accuracy. This talk presents the applications of QELMs in an industrial caseand two real-world systems from the Norwegian public sector (Cancer Registry and Oslo City). It also discusses challenges, future research directions, and other planned applications.

As quantum computing progresses toward real-world impact, ensuring industry and government readiness is paramount. This talk explores lessons from the UK’s National Quantum Computing Centre (NQCC), highlighting key strategies for fostering adoption, identifying and addressing barriers, and aligning quantum capabilities with end-user needs to build a resilient quantum ecosystem.

I shall present the update of the Q4Bio program which is a $50M supported challenge program.
