Abstract

Quantum Key Distribution (QKD) is one of the first commercially available quantum technologies and provides a means for distributing shared secret random keys between two users (Alice and Bob) in order to encrypt information sent between them. It has seen a number of long range demonstrations using either fibre or free-space links and many groups are actively working towards satellite communications [1]. Very recently, integrated photonics has developed to the point where it can provide a stable, compact, miniaturized and robust platform which can be used to implement complex photonic circuits including those required for QKD [2]. The phase stability of integrated photonics makes it particularly suitable for manipulating quantum information encoded in different time-bins, an encoding extensively used in fibre-based QKD communication systems.
