    "abstract": "Broadcast encryption allows the sender to securely distribute his/her secret\nto a dynamically changing group of users over a broadcast channel. In this\npaper, we just consider a simple broadcast communication task in quantum\nscenario, which the central party broadcasts his secret to multi-receiver via\nquantum channel. We present three quantum broadcast communication schemes. The\nfirst scheme utilizes entanglement swapping and Greenberger-Horne-Zeilinger\nstate to realize a task that the central party broadcasts his secret to a group\nof receivers who share a group key with him. In the second scheme, based on\ndense coding, the central party broadcasts the secret to multi-receiver who\nshare each of their authentication key with him. The third scheme is a quantum\nbroadcast communication scheme with quantum encryption, which the central party\ncan broadcast the secret to any subset of the legal receivers.",
