Unlocking the Future of Cryptography: From Mathematics to Quantum Materials 🔐

In this video, we explore how cryptography — once purely mathematical — is now entering a new era shaped by quantum physics and material science. For decades, encryption relied on computational hardness — the difficulty of solving large mathematical problems like factoring primes (RSA) or discrete logarithms (ECC). But with the rise of quantum computing, those assumptions are collapsing. This presentation covers from classical encryption to post-quantum cryptography, and finally into the emerging world where materials themselves secure information — using superconductors, graphene, and topological insulators
