Abstract

Quantum Key Distribution (QKD) is a method of sharing secret cryptographic keys between two parties (Alice, Bob) without the possibility that a third party (Eve) has eavesdropped on the conversation. There is much work towards commercialising QKD however this is largely restricted to large, expensive devices[1]. Since the average member of the public does not have dedicated single mode fiber connection to their house or the money for a dedicated QKD transmitter device (Alice), we propose a small and cheap device which could be distributed widely and brought to a central terminal (“Quantum ATM”, Bob) with which a secret key could be established with, for example, a bank[2].
