Abstract Quantum Key Distribution (QKD) offers unconditional security in principle. Many
QKD protocols have been proposed and demonstrated to ensure secure communication …

A reconfigurable intelligent surface (RIS)-aided multiple-input multiple-output (MIMO)
wireless communication system is considered in this paper wherein the transmitter, Alice …

Characterisation and mitigation of atmospheric turbulence is critical for free space optical
communication that relies on adaptive optics such as high bit rate coherent modulation or …

Networks of ground stations designed to transmit and receive at optical wavelengths through
the atmosphere offer an opportunity to provide on-demand, high-bandwidth, secure …

Continuous-variable (CV) quantum key distribution (QKD) allows for quantum secure
communication with the benefit of being close to existing classical coherent communication …

The standard way to measure the performance of existing continuous variable quantum key
distribution (CVQKD) protocols is by using the achievable secret key rate (SKR) with respect …

Optical fibers form the backbone of our modern communication systems with ubiquitous use
from connecting data centers to long distance links. In many cases, these links are used to …

Continuous variable quantum key distribution (CVQKD) uses the continuous quadratures of
light to share a secret key between a transmitter and receiver. The presence of an …
