We are truly living in a science fiction future where quantum code cracking is not a remote possibility but a near term risk we are planning for.
In Vernor Vinge's novel "A Fire Upon the Deep" one of the most valuable commodities were one time pads that are physically transported to communication nodes to enable unbreakable communication. The pads are split into three pieces that are XORed to create the actual pad to reduce risk of compromise.
