Quantum threats to cryptography has been fueled by Shor's and Grover's quantum algorithms and their derivatives. That has led a decade-long development of post-quantum cryptography algorithms and standards. While there are question lies about when Cryptanalytically Relevant Quantum Computers (CRQC) will be realized practically, they're imminent threats. In the meantime, Quantum computers and networks are evolving faster to take us closer to their realization in a practical and scalable manner, which will also help advance the development of CRQCs. In this talk, I will present how evolution of cryptography is shaping up, how to achieve quantum resistant security in a holistic manner and the development of quantum secure networks.
