Yes, but authentication is also a starting problem of public key crypto, and in QC there are quantum authentication protocoll (Wegman-Carter protocoll in QKD or Yoshito Kanari, Seong-Moo Yoo e A.Gregory) and quantum message authentication like the Quantum One Time Pad.

shortly QC protocolls (bb84, E91...) are used to generate and exchange the shared symetric key(truly random key as long as wanted), instead of of public key crypto. Then this key is used in classic channel with one time pad for communication. There are places where this protocolls are used in practice. in vien 2004 there was the first QC transaction betwen two banks. Toshiba Research Europe applied the QC in 2005 in a video-voip trasmission....

It not true at all. Quantum crypto solves the key exchange problem (and all problem related to classic crypto). I am not going to give more detail because is long, but quantum interference and quantum qbit teleport make sure that. Quantum Crypto was my bachelor thesis degree, I have studied it BB84 and E91 protocols are secure.
