The Quantum Technology Revolution and the Quantum-Safe Imperative

Michael Kasper

Fraunhofer Singapore Research

The opening keynote will provide an overview of quantum technologies (computing, sensing, communication, and others) for enterprise technology leaders. It will delve into the relevance of quantum technologies to enterprises and governments, and detail the implications of the arrival of quantum computing on current security paradigms — what is likely to break, why, roughly when, and which aspects of classical enterprise architecture and approaches it is likely to disrupt. Finally, it will explain what enterprises need to do to prepare for the quantum revolution, along with global developments in the sector, including accelerating timelines towards Q-Day.

The Quantum Countdown: Why Crypto Agility Is Now a Boardroom Strategy

Shaun Chen

Thales

The quantum threat is moving post-quantum cryptography from a technical modernisation initiative into a board-level risk management issue. While “Harvest Now, Decrypt Later” increases urgency around long-lived sensitive data, the broader challenge is how organisations modernise cryptographic trust across applications, identities, infrastructure, cloud services, supply chains, and operational technology without disrupting business operations.

This session will explore why PQC migration should not be treated as a one-time algorithm replacement exercise. Instead, security leaders need a crypto-agility operating model built on visibility, risk-based prioritisation, controlled transition, policy enforcement, and evidence. The discussion will provide practical guidance on how CIOs and CISOs can begin assessing exposure, engaging vendors, planning hybrid migration, and reporting readiness to executive stakeholders.

Architecting Singapore's National Quantum-Safe Network

Dr Haw Jing Yan

Centre for Quantum Technologies (CQT)

This presentation provides an overview of the National Quantum-Safe Network (NQSN) Testbed: a resilient, interoperable network designed to advance the deployment of quantum-safe technologies. Built on production-grade fibre infrastructure with a star-mesh topology, the testbed supports multiple quantum key distribution (QKD) protocols, post-quantum cryptography (PQC), and applications from diverse vendors. A centralised key and network management system enables seamless integration across these heterogeneous technologies. The presentation will showcase reference applications, including secure data-centre interconnects, edge computing, hybrid QKD–PQC encryption, and multi-layer integration across the OSI stack. It will also highlight recent NQSN standardisation initiatives in Singapore and internationally. Together, these developments demonstrate the feasibility, interoperability, and adaptability of quantum-safe technologies in complex, multi-vendor network environments.

Quantum isn’t the threat. Time is.

By the time you have identified where your Crypto lives it will be too late. Find out how a Cryptographic Abstraction Layer can reduce your PQC project from years to weeks with no application rework or Infrastructure rip and replace.

NETS's Journey Towards Quantum Readiness

Abhisarika Singh

NETS

This session will share NETS' journey towards quantum readiness, covering the quantum threat landscape, key risks to payment systems and sensitive data, NIST-approved PQC standards such as ML-KEM (Kyber), ML-DSA (Dilithium), FALCON, and SPHINCS+, as well as practical approaches for achieving crypto agility across enterprise environments.

Participants will gain insights into NETS' ongoing initiatives, including cryptographic inventory assessments, vendor engagements, proof-of-concept activities, collaboration with shareholder banks, and our multi-year roadmap aligned with industry guidance from NIST, CSA Singapore, and other global standards bodies. NETS has already begun foundational activities such as risk assessments, stakeholder awareness programmes, vendor evaluations, and quantum-readiness planning, with pilot implementations and broader migration activities forming part of our 2026-2031 strategy.

The objective of this session is to foster awareness, encourage industry collaboration, and share practical lessons learned as financial institutions prepare for the transition to a quantum-safe future. While large-scale cryptographically relevant quantum computers may still be several years away, organizations that begin planning today will be better positioned to protect critical payment infrastructure, customer data, and digital trust in the years ahead.

Q-Day — When and How?

Dr Anupam Chattopadhyay

Nanyang Technological University (NTU)

The session will outline where true quantum advantage is likely along with recent progress in error‑corrected operations, and highlight sharply reduced resource estimates for breaking RSA and ECC. Although experts still place practical quantum attacks about a decade away, IBM’s roadmap and Neven’s Law show rapid scaling toward large‑scale machines. The presentation will close with guidance for transitioning to post‑quantum security through NIST‑standardized algorithms, cryptographic agility and a realistic, measured approach to Q‑Day preparation.

HSBC's Quantum-Safe Journey

Dr Cai Yu

HSBC

HSBC’s quantum-safe journey is a risk-led programme to maintain trust as quantum computing advances at pace, putting today’s asymmetric cryptography at risk. Dr Yu will cover the bank's operational approach—senior leadership sponsorship, cross-team collaboration, and central capabilities enabling decentralised migrations—alongside what it's doing now and where it's heading next. Dr Yu will also set out how HSBC prioritises using discovery and risk, strengthens third-party management, and develops the talent needed to deliver at pace.

From Awareness to Action: The CISO’s Challenge

Kamran Rafiq

Ministry of Health Office for Healthcare Transformation (MOHT)

This session will explore the practical barriers security leaders face when trying to implement post-quantum cryptography (PQC) across complex IT environments. The speaker will discuss organizational, technical, and ecosystem challenges, such as gaining visibility of cryptographic assets, addressing legacy systems, and navigating the readiness of vendors and technology platforms. The presenter will also discuss performance and integration concerns, how to prioritize PQC alongside other security investments, and effective ways to communicate quantum-related risks and timelines to executive leadership.
