What Is “Quantum Supremacy” and Why It Sounds Scary “Quantum supremacy” refers to the point where quantum computers outperform classical ones at specific tasks. While this sounds abstract, the potential consequences are very real — especially for cryptography. Quantum algorithms likeShor’s could, in theory, break RSA and elliptic curve cryptography (ECC), the backbone of internet security.Grover’s algorithm can also weaken symmetric encryption by reducing brute-force resistance....| Vault12
“Quantum supremacy is important both in its own right and as a benchmark or step toward something further. But my theory is that quantum supremacy cannot be achieved, and this is based on a…| Combinatorics and more
