Dominic Jainy is a distinguished IT professional whose career has been defined by the early adoption of transformative technologies, including artificial intelligence, machine learning, and blockchain. As the digital landscape faces the looming shadow of quantum computing, Dominic has turned his focus toward the essential task of securing the global telecommunications fabric. With deep insights into how large-scale operators like Singtel are navigating this shift, he provides a pragmatic bridge between complex cryptography and the operational realities of national infrastructure. His expertise is particularly relevant today in 2026, as the industry moves from experimental quantum-safe trials toward full-scale commercial resilience, ensuring that the sensitive data of governments, banks, and citizens remains protected in a post-quantum world.
The following discussion explores the critical themes of quantum-safe network migration, beginning with the immediate risk posed by the decade-long lifecycles of current telecom hardware. We examine the necessity of a multi-layered ecosystem that involves regulators, vendors, and end-users to manage the sheer complexity of modern mobile and fiber cores. The conversation also highlights the strategic blending of Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) into a hybrid defense model. Finally, we look at the transition from research-led initiatives like the National Quantum Safe Network to operational readiness, where the focus shifts to making advanced security an invisible yet foundational component of the connectivity services that enterprises depend on every day.
Telecom infrastructure like passive optical networks often stays in service for a decade or more. How does this extended lifespan influence the urgency for quantum-safe migration right now?
The reality of the telecommunications industry is that the hardware we install today isn’t just for this year; it is designed to serve as the backbone of society for at least 10 years or more. When you consider that mobile network generations and passive optical networks have such long operational lives, the timeframe for a quantum threat suddenly feels very immediate rather than a distant concern. If we wait until quantum computers are commercially ubiquitous to start upgrading, we will have already missed the window to protect the data flowing through infrastructure deployed today. This creates a high-stakes mismatch where sensitive information—from healthcare records to banking transactions—could be intercepted now and stored for decryption once quantum capabilities catch up. That is why we can’t treat this as a simple software patch; it is a massive network transformation that takes several years of planning and physical upgrades to complete. By starting this migration now, we are ensuring that the 10-year lifecycle of our current infrastructure doesn’t become a decade-long vulnerability for our most critical sectors.
Given the immense complexity of modern networks—spanning from mobile cores and radio access to billing systems and APIs—why is a collaborative ecosystem more effective than a single-product solution?
Modern telecom environments are incredibly sprawling organisms, and no single product or vendor can possibly secure every touchpoint, from the optical transport layer to the cloud-native applications and IoT platforms. Singtel has identified that a successful quantum-safe transition requires a synchronized effort across infrastructure, software, vendors, and regulators because every part of the network is interconnected. For instance, working with Singapore’s Infocomm Media Development Authority and the Center for Quantum Technologies allows us to align technical standards with national security requirements. We also have to engage with diverse partners like Ericsson for mobile networks, while simultaneously working with firewall vendors and cloud providers to ensure there are no gaps in the defense. This ecosystem approach is vital because we are critical infrastructure providers; our customers, including government agencies and financial institutions, trust us to anticipate these challenges before they become emergencies. It is a massive coordination task that involves educating everyone from software developers to corporate boards about the shared responsibility of digital resilience.
There is often a debate between using physical Quantum Key Distribution and software-based Post-Quantum Cryptography. How does a hybrid approach bridge the gap between these two technologies?
Rather than viewing QKD and PQC as competitors, we see them as complementary forces that address different physical and logical needs within the network. Quantum Key Distribution is an exceptional tool for environments where we have direct access to fiber infrastructure, such as connecting major data centers, government buildings, or the headquarters of financial institutions where the highest level of physical security is required. However, the limitation of QKD is that you can’t run a dedicated fiber line to every single mobile device or remote cloud endpoint, which is exactly where Post-Quantum Cryptography shines. PQC is a software-based approach that can be deployed across existing systems, providing quantum-resistant protection to endpoints that aren’t physically linked via optical fiber. By combining these two—creating hybrid keys that pull from both QKD and PQC infrastructures—we can extend a robust shield across the entire network architecture. This ensures that while the core fiber backbone is physically secured, the virtualized edges and cloud segments are equally resilient against future cryptographic attacks.
As we transition from experimental phases to broader commercial adoption, what are the primary challenges in making quantum security practical for the average enterprise?
The shift from the initial National Quantum Safe Network to the current NQSN+ phase is really about moving from a “proof of concept” to full-scale operational readiness. The challenge lies in making the complex “plumbing” of quantum security—things like key management, orchestration, and interoperability—completely seamless and invisible to the end user. When an enterprise buys a connectivity service, they aren’t looking to manage individual cryptographic components; they expect a secure “pipe” that works regardless of the underlying technology. We are working to ensure that different systems can talk to each other across an end-to-end service, so that a CIO or CISO doesn’t have to worry about the specific mechanics of the quantum-safe layer. This involves a heavy focus on commercialization and standards, ensuring that our products are as easy to consume as standard internet or cloud services. Ultimately, our goal is to provide a service where the security is a fundamental, integrated feature that gives businesses the confidence to operate without needing to be experts in quantum physics themselves.
What is your forecast for the adoption of quantum-safe networking?
I anticipate that over the next few years, quantum-safe protocols will rapidly shift from being a specialized, “early-adopter” feature to becoming the baseline global standard for all critical infrastructure. As more governments and regulatory bodies recognize the “store now, decrypt later” risk, we will see a mandatory push for hybrid architectures that utilize both QKD and PQC across national networks. I expect that by the end of this current decade, the integration of these technologies will be so deep that it will be a standard requirement in every enterprise service level agreement, particularly in the finance and healthcare sectors. We will see a shift in the sensory experience of digital trust, where the hidden complexity of quantum-resistant keys provides a silent but absolute foundation for the global economy. Those who have invested in building these ecosystems today will be the ones who define the security landscape of the 2030s, turning potential vulnerability into a significant competitive advantage in a world where data is the most valuable asset.
