Quantum communication is possible with pure state

TL;DR

This paper demonstrates that quantum communication can be achieved using pure states, challenging the common belief that pure states are insufficient due to their zero quantum entropy, by leveraging geometric properties of entanglement.

Contribution

It reveals that pure states can facilitate quantum communication through geometric effects of entanglement, overturning previous assumptions.

Findings

Quantum communication is possible with pure states.

Geometric effects of entanglement enable this possibility.

Challenges the belief that pure states cannot be used for quantum communication.

Abstract

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.
