Abstract

We present an information-theoretically secure protocol for the transmission of a quantum state between an anonymous sender and an anonymous receiver. The anonymity is perfect and so is the privacy of the message. No assumption is made on the number of honest participants and this leads to a protocol in which a single participant can cause an abort. Unless the receiver is corrupt, the quantum state is never destroyed; thus the state is either transferred to the receiver or it remains in the hands of the sender.
