Abstract

The development of quantum computing threatens the security of our currently widely deployed cryptographic algorithms. While signicant progress has been made in developing post-quantum cryptography (PQC) standards to protect against future quantum computing threats, the U.S. government's estimated 7.1 billion transition cost for non-National Security Systems alone, coupled with an aggressive 2035 deadline, will require sustained funding, research, and international coordination to successfully upgrade existing cryptographic systems.
