Position paper on Quantum Key Distribution

This paper is written to assist policy and decision makers in making informed judgements about the use of Quantum Key Distribution (QKD). QKD is a technology that is getting more and more attention. It claims unprecedented levels of security against attacks from both classical and quantumcomputers. QKD attempts, through an insecure quantum channel, to exploit quantum effects to allow two external parties to agree on a secret key. However, in practice, this technology still has limitations.
