A security analysis of 11 deployed QKD use cases finds that QKD provides little or no advantage over PQC or pre-shared keys in most scenarios, with only OTP-based short-distance links offering a clear benefit.

abstract
We report the co-propagation, over 50 km of SSMF, of the quantum channel (1310 nm) of a QKD system with ~17 dBm total power of DWDM data channels (1550 nm range). A metric to evaluate Co-propagation Efficiency is proposed.

A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography
A security analysis of 11 deployed QKD use cases finds that QKD provides little or no advantage over PQC or pre-shared keys in most scenarios, with only OTP-based short-distance links offering a clear benefit.
