On Information, Quanta, and Context

Valéria Loscrì, Anna Maria Vegni

Quantum phenomena represent a natural direction for developing nanotechnology, since it has to be considered as a new scale where new phenomena can occur and can be exploited for information purpose. Specific quantum particles are phonons, the quanta of mechanical vibrations (i.e., acoustic excitations), that can be analyzed as potential information carriers in a body network context.

Nanotechnology, as enabler of the miniaturization of devices in a scale ranging from 1 to few hundreds of nm , represents a viable solution for “ alternative” communication paradigms that could be effective in complex networked systems, as body area networks. Traditional communication paradigms are not effective in the context of joint body and nano-networked systems, for several reasons, and then novel approaches have been investigated such as nanomechanical, electromagnetic, acoustic, molecular, etc. On the other hand, quantum phenomena represent a natural direction for developing nanotechnology, since it has to be considered as a new scale where new phenomena can occur and can be exploited for information purpose. Specific quantum particles are phonons, the quanta of mechanical vibrations (i.e., acoustic excitations), that can be analyzed as potential information carriers in a body networked context. In this paper we will focus on the generation of phonons from photon-phonon interaction, by irradiating a sample of human tissue with an electro-magnetic field, and then we will theoretically derive the information capacity and the bit rate in the frequency range [103- 1012] Hz.

We develop an epistemological backbone for the blur programme: a picture in which quanta are not optional microscopic details but structural consequences of finite information and fixed blur. The starting point is a three-layer view: an unreachable Blank (reality in full), channels with native blur (resolution, bandwidth, memory), and the histories we reconstruct from blurred data. Once a blur structure and an information budget are fixed, every physically accessible configuration decomposes into quanta: discrete information grains that can be organised into countable families. This quantization persists as blur is refined and survives even in the formal "blur $=0$" limit used in continuum models. We formulate this as a Quanta Representation Principle: in any quantum universe-a universe where finite systems cannot leak infinite information-every observable channel has a discrete, blur-stable basis of quanta. Continuous descriptions (fields, densities, wavefunctions) are then seen as emergent summaries of these grains, not competitors to them. A blackbody-style inverse argument shows that if such quanta did not exist, finite systems would be able to encode arbitrarily many bits into arbitrarily small energetic deviations, violating no-free-information constraints. We conclude with a universe-level distinction: either one works in wild universes where finite systems can carry infinite information (and blur collapses), or in quantum universes where quanta are unavoidable and survive every reasonable limit, including blur $\rightarrow 0$ in PDE models.
