Information-Theoretic Estimates of Classical and Quantum Communication and Processing at Nanoscale

摘要

This paper examines fundamentals of classical, hybrid and quantum information technologies which are the bases of computer science and computer engineering. We define, analyze and evaluate classical and quantum-mechanical information measures pertained to communication and processing at nanoscale. The macroscopic and microscopic physical communication and processing platforms and hardware are considered. Macroscopic and microscopic systems operate on the electron- and photon-induced transductions. However, conventional electrostatic and quantum processing are fundamentally distinct. There are major differences in device physics, utilized phenomena, device- and system-level solutions, arithmetics, software and hardware solutions, etc. This paper contributes to design and analysis of multi-physics quantum→classical communication and processing. We advance a knowledge base in cognizant areas across disciplines. Our findings enable existing and future communication, sensing, information fusion, computing and processing platforms. These enable technical readiness, technological capabilities and commercialization capacities by developing relevant tools, methods and practical schemes.
