Special Issue Information

Dear Colleagues,

The field of quantum information, cryptography, and computation has witnessed remarkable advancements over the past few decades, promising to revolutionize the way we process and secure information. This Special Issue aims to explore the latest developments, challenges, and opportunities in these interconnected domains. The primary objective of this Special Issue is to provide a comprehensive platform for researchers, practitioners, and academics to present their cutting-edge research findings, innovative methodologies, and practical applications related to quantum technologies. We seek to highlight the theoretical foundations, experimental breakthroughs, and integration of quantum principles into existing computational and cryptographic frameworks. We invite scholars and researchers from diverse backgrounds to contribute original research articles, reviews, and case studies that address these topics. By bringing together a collection of high-quality papers, this Special Issue aims to advance the understanding and practical implementation of quantum information, cryptography, and computation.

Quantum secure direct communication (QSDC) is convenient for the direct transmission of secure messages without requiring a prior key exchange by two participants, offering an elegant advantage in transmission security. The traditional implementations usually focus on the discrete-variable (DV) system, whereas its continuous-variable (CV) counterpart has attracted much attention due to its compatibility with existing optical infrastructure. In order to address its practical deployment in harsh environments, we propose a microwave-based scheme for the CV-QSDC that leverages entangled microwave quantum states through free-space channels in cryogenic environments. The two-step scheme is designed for the secure direct communication, where the classical messages can be encoded by using Gaussian modulation and then transmitted via displacement operations on microwave quantum states. The data processing procedures involve microwave entangled state generation, channel detection, parameter estimation, and so on. Simulation results demonstrate the feasibility of the microwave-based CV-QSDC, highlighting its potential for secure communication in integrated superconducting and solid-state quantum technologies.
