The Public Sector Podcast: Trust That Outlives Technology: Protecting Public Data in the Quantum Era

Episode Overview

In this episode, Sandeep Taileng, Co Chair - National Committee for Information Access & Protection Requirements and Information Security Leader, State Trustees (Victoria) demystifies quantum computing and explains why quantum readiness is becoming a present-day responsibility, not a future problem. He breaks down complex concepts like qubits, post-quantum cryptography and “harvest now, decrypt later” in simple terms, and explains why organisations need to start thinking about how long their data needs to remain secure — not just whether it’s secure today.

The conversation also explores the idea of a fiduciary duty to protect data over the long term, the growing global investment in quantum technologies, and what a practical quantum readiness roadmap looks like. From building an encryption inventory to working with vendors and addressing skills gaps, this episode focuses on how organisations can start preparing now in a structured and realistic way.

Key Themes

• Quantum computing explained simply
• The fiduciary responsibility to protect long-life data
• “Harvest now, decrypt later” and long-term data risk
• Global investment and regulatory momentum in quantum
• Building a quantum readiness roadmap
• Vendor, supply chain and skills challenges
• Crypto-agility and long-term resilience

What You’ll Learn

• The difference between classical computing and quantum computing
• Why quantum is a data longevity problem, not just a technology problem
• What “harvest now, decrypt later” means in practice
• How long-term data retention changes your risk exposure
• What organisations should do first to prepare for post-quantum cryptography
• How to build a phased roadmap instead of a large one-time transformation
• Why working with vendors and suppliers is critical for quantum readiness

Key Takeaways

• Quantum risk is a long-term data problem, not just a future technology problem.
• Data being collected today could be decrypted years in the future.
• Organisations have a fiduciary responsibility to protect sensitive data long-term.
• You don’t need to solve everything now, but you do need a plan.
• Start with encryption discovery and build a phased migration roadmap.
• Work with vendors and suppliers — you don’t have to solve this alone.
• Resilience belongs to organisations that prepare early.

Why You Should Listen

If you work in cyber security, risk, technology, data, or government, this episode provides a clear and practical introduction to quantum risk and post-quantum cryptography. It explains why quantum matters now, what the real risks are, and what organisations can realistically do today to start preparing without panic or massive upfront cost.

Memorable Quotes

• “Quantum is a data longevity problem.”
• “Your data is being harvested today to be decrypted tomorrow.”
• “Are we still meeting our fiduciary duty if data is decrypted in 10 years?”
• “You don’t need a quantum computer to be a quantum hacker.”
• “Don’t react later — prepare now.”
• “Resilience belongs to those who prepare, not those who react.”
