This paper introduces the first Rydberg atomic quantum receiver (RAQR) for underwater wireless optical communications (UWOC). Unlike conventional RF-oriented Rydberg receivers, the proposed architecture exploits direct optical excitation of an atomic transition, enabling a compact threelevel configuration in which the...

Distributed MIMO networks can improve coverage and reliability through spatial diversity, but their performance is often limited by external interference and fixed duplex operation. This paper develops an interference-aware distributed MIMO framework that integrates flexible duplexing (FlexD) with maximum ratio transmi...

The results show that, at sufficiently high signal-tonoise ratio (SNR), the information rate becomes largely insensitive to PN power allocation, enabling near-perfect secrecy with M - QAM modulation-highlighting a key departure from Shannoncapacity-based secrecy analyses and underscoring the practicality of finite-alph...
