New Zealand and Korea are partnering on three major research projects to improve long-distance quantum communication. The work aims to make online data safer, support next-generation networks, and position both countries as global leaders in quantum technology.
New Zealand has taken a big step toward the future of secure communication by launching three joint research projects with the Republic of Korea. The partnership focuses on quantum communication, a fast-growing field that could transform how governments, businesses, and everyday users keep their digital information safe.
The projects are part of the New Zealand – Korea Joint Research Partnerships Programme, a triennial funding initiative that supports scientific collaboration between the two nations.
Why Quantum Communication Matters
Quantum communication uses the laws of physics to protect information. It has the potential to make online banking safer, secure health records, and protect sensitive information from cyber attacks.
However, there are major challenges today. Quantum signals must be created, sent, and preserved over long distances without losing their special properties. Solving these issues is essential for future quantum networks.
A Strategic Choice for 2025
Heather Penny, MBIE Manager Specialised Investments, says quantum communication was chosen as the theme for the 2025 funding round because breakthroughs in this area can deliver wide benefits for both countries. Stronger cybersecurity, safer digital services, and new commercial opportunities are among the expected outcomes.
The call for proposals was managed by the Dodd-Walls Centre for Photonic and Quantum Technologies on behalf of MBIE.
Project 1: Building Quantum Repeaters for Long Distance Security
Researchers:
- University of Otago
- Korea Advanced Institute of Science and Technology (KAIST)
These teams are developing quantum repeaters, which act like ultra-secure relay stations. The repeaters store and resend quantum information using rare-earth quantum memories built inside advanced photonic circuits.
What this will enable
- Ultra-secure communication across cities and countries
- Scalable quantum networks and modular quantum computers
- Stronger leadership for NZ and Korea in global quantum technology
Project 2: A Chip-Based Quantum Light Source for Everyday Use
Researchers:
- University of Auckland
- KAIST
This project aims to replace large optical machines with a compact chip that creates quantum light. The goal is to make quantum key distribution (QKD) affordable and usable across current telecom networks.
What this will enable
- Secure communication for government, defence, and finance
- Long-term security options for everyday users
- Local manufacturing of quantum components and faster commercialisation
- Growth in integrated quantum photonics research
Project 3: Linking Light and Microwave Quantum Signals
Researchers:
- University of Otago
- Kyung Hee University, Korea
This team is developing an interface that allows different quantum systems to talk to each other. The technology uses surface acoustic waves and light resonators to convert signals smoothly between light and microwaves.
What this will enable
- Seamless and secure transfer of signals across quantum networks
- New foundations for hybrid quantum computing
- Next-generation communication and information systems
Why This Partnership Matters
The collaboration takes advantage of New Zealand’s strengths in quantum physics and photonics, paired with Korea’s engineering skills and deep expertise in advanced technology.
Heather Penny notes thata partnership with like-minded countries accelerates progress and creates opportunities that neither nation could achieve alone.

Conclusion
This partnership between New Zealand and Korea signals a strong step toward building secure, future-ready communication systems. If successful, the research could lead to safer online services, powerful new quantum networks, and advanced technologies that benefit people, businesses, and national security on both sides of the partnership.
