Extends classical steganography protocols to quantum information transmission

Shows practical utility in nonclassical state teleportation

Abstract

In a previous work we have discussed a theoretical grounding for classical steganography using quantum Fock and coherent states in an optical channel, building on previous work by Wu et al. In that work, we discussed protocols which disguise communications to mimic the thermal state of a harmonic oscillator. In this work we will extend this to transmission of quantum information, and demonstrate the utility of steganographic entanglement sharing in practical contexts like nonclassical state teleportation, even with the presence of an active eavesdropper.
