quantum communication

hello guys!
congratulation to all, for having our own forum on nanophotonics
for beginning Ive uploaded a very useful ebook about "Quantum Communication"by McMahon.I think its 3rd Ch. has lots of benefits to everyone who wants to become familiar with quantum stats, quantum bits, operator and matrix algebra and so forth.the other chapters are good for ones searching in the field of quantum communication.Both links are the same,one from rapidshare.com and one from 2shared.com
