Dense coding with mixed state and steerability

Quantum Physics 2023-01-25 v2

Abstract

Mixed state can be used in dense coding. We have analyzed here that maximally entangled mixed states like Werner state is dense codeable for a certain range of state parameter whereas for some wider range of the state parameter the state is `steerable' but cannot be used in dense coding. For qutrit system we consider isotropic states and have found similar characteristics, like the states are `steerable' for a range of state parameter but for a sub range of that steerability range only, the states are dense-codeable.

This paper has some errors pertaining to my understanding of the concept of steering, for which it has been withdrawn
