“…Hence, in quantum information processing endeavors necessitating the simultaneous measurement of photonic fields at spatially disparate locales -examples being quantum Multiple-Input Multiple-Output (MIMO) communication systems and quantum multi-access links [74]- [78] -it becomes imperative to account for the precise commutator value. In practical scenarios such as the design of optimal receivers for quantum MIMO channels, the commutator of photon counting rates emerges as an external constraint pivotal to the core of digital receiver design optimization [76].…”

<p>We explore essential factors pertaining to the spatial directivity of quantum radiating source systems (QSSs), encompassing quantum antennas and quantum sensors. Our primary focus is on their capacity to control the emission of photons in specific spatial directions. We present a comprehensive definition of quantum directivity, drawing inspiration from Glauber’s photon detection theory. This definition closely parallels the framework of analogous concepts in classical antenna theory. By conducting thorough conceptual and mathematical analysis, we address the challenge of characterizing the directive properties of a general QSS. Essentially, our approach presents a computational model that relies solely on the radiation field operator’s density as input.</p>

“…To meet the explosion of data transmission, multiple-input multiple-output (MIMO) technology has been widely used in wireless communication nowadays. MIMO system with multiple antennas at both the transmitter and receiver side brings benefits on data throughout and communication range with limited bandwidth and transmit power [70]. THz QKD with SISO and MIMO systems was introduced in Refs [64] and [71], with the main focus on midand far-infrared frequency ranges (10THz-40THz) at room temperature (T= 296 K).…”

“…Quantum key distribution (QKD) can help to achieve the goal of high-level unconditional security with the power of quantum physics [64][65][66][67]. QKD could be divided into discrete variables (DVQKD based on single photon sources and detectors) and continuous variables (CVQKD based on standard communication systems) [65][66][67][68][69][70][71][72][73][74][75][76][77][78]. CVQKD uses coherent homodyne detection instead of single photon detection [68] and could be integrated with nextgeneration communication systems [69].…”

With the exponentially increased demands for large bandwidth, it is important to think about the best network platform as well as the security and privacy of the information in communication networks. Millimetre (mm)-waves and terahertz (THz) with high carrier frequency are proposed as the enabling technologies to overcome Shannon's channel capacity limit of existing communication systems by providing ultrawide bandwidth signals. Mm-waves and THz are also able to build wireless links compatible with optical communication systems. However, most solid-state components that can operate reasonably efficiently at these frequency ranges (100GHz-10THz), especially sources and detectors, require cryogenic cooling, as is a requirement for most quantum systems. Here, we show that secure mm-waves and THz QKD can be achieved when the sources and detectors operate at cryogenic temperatures down to T= 4K. We compare singleinput single-output (SISO) and multiple-input multiple-output (MIMO) Continuous Variable THz Quantum Key Distribution (CVQKD) schemes and find the positive secret key rate in the frequency ranges between f=100 GHz and 1 THz. Moreover, we find that the maximum transmission distance could be extended, the secret key rate could be improved in lower temperatures, and achieve a maximum secrete communication distance of more than 5km at f=100GHz and T=4K by using 1024×1024 antennas. Our results for the first time show the possibility of mm-waves and THz MIMO CVQKD with the system operating at temperatures below T= 50K, which may contribute to the efforts to develop next-generation secure wireless communication systems and quantum internet for applications from inter-satellite and deep space to indoor and short-distance communications.

There is a problem that it is difficult to express and understand the PQKD (Parallel Quantum Key Distribution) processes with quantum entanglement states for its novelty and complexity. To solve this problem, the control idea is adopted to model the PQKD system for the design of the corresponding PQKD schemes using the tool of UML (Unified Modeling Language). The results of demon animations by the UML models show that the dynamic processes of PQKD with entangled states can be illustrated more clearly and intuitively than before, while the PQKD control system remains the advantage of unconditional security. These models are important to develop large-capacity long-distance PQKD.
