Secret Broadcasting of W-type state

TL;DR

This paper presents a protocol for secretly broadcasting W-type states among three distant partners using a novel local cloning operation, enabling the generation of two W-type states from an initial shared state.

Contribution

Findings

Successful protocol for secret broadcasting of W-type states

Novel local cloning operation demonstrated

Potential applications in secure quantum communication

Abstract

In this work we describe a protocol by which one can secretly broadcast W-type state among three distant partners. This work is interesting in the sense that we introduce a new kind of local cloning operation to generate two W- type states between these partners from a W-type state initially shared by them.
