- Additional information
- For quantum communications technologies to become ubiquitous, they need to be implemented in network settings, with minimal trust on network nodes and inexpensive equipment for end users. This work, funded by H2020, EPSRC, and other national agencies, addresses the problem by implementing a star-topology quantum network, with a shared entanglement source in the middle and passive receivers for end users. This enables secret key exchange among multiple pairs of users, as well as other applications in quantum cryptography and secure multipartite quantum computing. An extended version of this network (to 16 users) is now operating at the co-authors’ Bristol site.
