This page came about because of how long it took PQC to get standardized. This was a slow enough process that a whole slew of QKD vendors arose and sold a lot of products promising this as a solution to dealing with quantum computers and harvest now decrypt later attacks. Many of those products did not do a great job at actually preventing listening in on their lines since QKD is an ongoing field of research where new issues are routinely being discovered.
