QCI.DK: Understanding Quantum Key Distribution
How can we protect sensitive data against future cyber threats? And what role can quantum communication play in securing our digital infrastructure?
The QCI.DK project has produced a short four-part video series introducing Quantum Key Distribution (QKD) and explaining why quantum communication is becoming increasingly important for cybersecurity.
The videos take viewers from the emerging threat landscape and the history of QKD to the principles behind the technology and the challenge of “harvest now, decrypt later”—where encrypted data collected today could potentially be decrypted by quantum computers in the future.
