Quantum communication is possible with pure state
<|reference_start|>Quantum communication is possible with pure state: It is believed that quantum communication is not possible with a pure ensemble of states because quantum entropy of pure state is zero. This is indeed possible due to geometric consequence of entanglement.<|reference_end|>
