KNUST Hosts Workshop on Quantum Technology to Improve Secure Digital Communication

The Kwame Nkrumah University of Science and Technology (KNUST) has taken a bold step in advancing scientific education by hosting a hands-on workshop on quantum technology. The event, organized by the Ghana Photonics and Optics Laboratory (GPOL), focused on how quantum systems can be applied to strengthen secure digital communication.

The training centered on Quantum Key Distribution (QKD), a revolutionary method that uses the laws of quantum physics to encrypt sensitive information such as emails, banking data, and private messages. QKD ensures that communication remains secure by detecting any attempt at eavesdropping, making it more advanced than conventional encryption systems. The workshop formed part of activities marking the International Year of Quantum Science and Technology (2025), aimed at raising global awareness of quantum applications.

Mr. Silas Ifeanyi, Engineering Education Developer at the Pearl Sullivan Engineering IDEAs Clinic, University of Waterloo, demonstrated how a QKD kit works. “Quantum key distribution uses single-photon signals to establish a secure secret key. This makes it possible to detect if there is an eavesdropper tapping into your message,” he explained.

He emphasized that as computing power advances, current cryptographic methods are becoming increasingly vulnerable, making quantum technology essential for the future of secure communication.

Participants were given the opportunity to:

Assemble quantum communication systems themselves.

Apply their learning to real-world cryptography exercises.

Gain practical exposure to how quantum mechanics can be harnessed for cybersecurity.

Traditional encryption methods are at risk as quantum computing evolves, and quantum technology offers a next-generation solution for protecting sensitive information. By training students and researchers, KNUST is positioning Ghana as a leader in quantum science education and innovation.
