  Quantum communication is rapidly gaining popularity due to its high security
and technological maturity. However, most implementations are limited to just
two communicating parties (users). Quantum communication networks aim to
connect a multitude of users. Here we present a fully connected quantum
communication network on a city wide scale without active switching or trusted
nodes. We demonstrate simultaneous and secure connections between all 28
pairings of 8 users. Our novel network topology is easily scalable to many
users, allows traffic management features and minimises the infrastructure as
well as the user hardware needed.
