The optical fibre is an essential tool for our communication infrastructure since it is the main transmission channel for optical communications. The latest major advance in optical fibre technology is space-division multiplexing, where new fibre designs and components establish multiple co-existing data channels based on light propagation over distinct transverse optical modes. Simultaneously, there have been many recent developments in the field of quantum information processing, with novel protocols and devices in areas such as computing and communication. Here, we review recent results in quantum information based on space-division multiplexing optical fibres, and discuss new possibilities based on this technology.

光纤是我们通信基础设施的重要工具，因为它是光通信的主要传输通道。光纤技术的最新重大进展是空分复用，其中新的光纤设计和组件根据光在不同横向光学模式上的传播建立多个共存的数据通道。同时，在量子信息处理领域中已经有了许多新的发展，在诸如计算和通信等领域具有新颖的协议和设备。在这里，我们回顾基于空分多路复用光纤的量子信息的最新结果，并讨论基于该技术的新可能性。
