- Sponsored by a Leverhulme Trust research fellowship and the EPSRC, through the UK quantum communications hub, this work rigorously proved the security of the high-rate quantum cryptographic protocol of measurement-device-independence in the symmetric configuration where the relay is exactly in the middle between the users. The result of this research paved the way for the design and development of star networks where many users are able to securely communicate one with each other by connecting to a middle generally-untrusted relay. From this point of view, this work represented a step forward in the development of high-rate secure quantum networks.
