SINGAPORE/KUALA LUMPUR, 31 August 2025 – Quantum computing is shifting from sci-fi fantasy to global tech imperative. With quantum-driven innovation poised to unlock revolutionary advances in healthcare, logistics, and artificial intelligence, Singapore and other Asian economies are doubling down on investments. At the same time, the rise of quantum poses serious cybersecurity threats, making the race for quantum safety as urgent as it is strategic.
Quantum: The Promise and the Peril
In Singapore’s National Day Rally, Prime Minister Lawrence Wong framed quantum computing as a “completely new way of processing information” that could transform industries over the next decade. Backed by a national strategy that includes S$300 million in research funding, the country is preparing for the quantum leap. McKinsey projects quantum technologies could expand from US$4 billion in 2024 to US$97 billion by 2035—highlighting a rapidly accelerating global market.
Quantum’s power lies in qubits, which harness superposition and entanglement to process possibilities simultaneously—enabling computations beyond the reach of classical systems. Applications range from drug discovery and AI model optimisation to solving complex logistical puzzle shapes around climate simulation and material science.
Yet the technology’s power also challenges the foundation of digital trust. Quantum computers could crack existing encryption, threatening a wave of “harvest-now-decrypt-later” attacks. More than 70% of major firms are already planning for quantum-safe strategies within five years.
Building Asia’s Quantum Ecosystem
Singapore, aiming to position itself as a frontier tech hub, launched its National Quantum Strategy to advance talent development, infrastructure, industry innovation, and global partnerships. The National Quantum Office now leads the coordination of policy and research, while enterprise efforts such as Singtel’s quantum-safe network and OCBC’s quantum roadmap underscore early private-sector adoption.
Singapore is not alone. Across Southeast Asia, nations like Malaysia are investing in AI and cybersecurity. Malaysia projects its digital economy to contribute over 25% of GDP by 2025, backed by strategic investments in AI frameworks, talent development, and cybersecurity infrastructure. Malaysia’s focus on quantum-safe cryptography and AI illustrates the region’s recognition of these converging technological priorities.
Regional & Global Implications
For The Ledger Asia’s readers, understanding quantum computing is essential. Southeast Asia’s embrace of quantum signals readiness not only for tomorrow’s industries but also for safeguarding digital governance. Quantum disruption is not just technical—it is economic, diplomatic, and societal.
Countries that invest in quantum readiness—from policy and skills development to cybersecurity—will enjoy economic dividends and competitive edge. Moreover, regional collaboration on crypto standards, talent exchanges, and startup ecosystems will determine Asia’s leadership in the emerging quantum frontier.
