  Conference key agreement (CKA), or multipartite key distribution, is a
cryptographic task where more than two parties wish to establish a common
secret key. A composition of bipartite quantum key distribution protocols can
accomplish this task. However, the existence of multipartite quantum
correlations allows for new and potentially more efficient protocols, to be
applied in future quantum networks. Here, we review the existing quantum CKA
protocols based on multipartite entanglement, both in the device-dependent and
the device-independent scenario.
