N2 - We propose the first protocol for anonymous distribution of quantum information. It can be used to implement channel with an anonymous sender, channel with an anonymous receiver or channel with both the sender and the receiver being anonymous. Our protocol achieves anonymity and message secrecy with unconditional security against any number of fully cooperating malicious participants. It uses classical anonymous transfer as a primitive. It overcomes disruption of the protocol, but the number of disrupters is limited by the capacity of the quantum erasure channel with one-way classical communication implying that there must be strict majority of non-disrupting participants. A different version of the protocol tolerates any number of disrupters, but is secure only when the receiver does not actively cooperate with other corrupted participants. A simplified version of the protocol (without detection of disrupters) was experimentally realized for 5 participants, but with different motivation, see \cite{Zhao.Chen.ea-Experimentaldemonstrationof-2004}.
