The Australian Signals Directorate’s Australian Cyber Security Centre has released the third publication in its Quantum Technology Primer series for cyber security leaders. This instalment explores quantum communications and the potential impacts they may have on the future cyber security landscape.

Quantum communications use principles of quantum physics to encode and transmit information in new ways. These technologies may offer unique security properties for transmitting sensitive data in the future. However, they face many practical constraints today, including short transmission distances, specialised hardware requirements, and a lack of mature standards.

Organisations can prepare now by factoring emerging risks into their cyber security planning and posture. Proactive measures grounded in cyber security best practice can help manage these risks, such as planning for the transition to post-quantum cryptography.
