Abstract
Quantum steganography is the extension of steganography to the quantum setting, wherein a quantum protocol (e.g.: a quantum error-correcting code) is used to hide classical or quantum information. Because of the unique nature of quantum states and channels, quantum steganography can be stronger than classical steganography. A lot of effort has been devoted to characterizing how much information can be embedded into various quantum channels with or without noise, and recently, several quantum steganography protocols have been developed and analyzed that improve on earlier work by exploiting a concept known in information theory as channel resolvability. This paper first provides a concise background survey of specific topics from relevant disciplines in classical as well as quantum information theory, and then presents a formulation of the problem concerning the characterization of the steganographic capacity for a specific type of quantum channel called the lossy bosonic channel.
