QS 07 Can Quantum Computers Break Modern Cryptography? 🛡️

Multiple choice time! What's the kind of cryptographic ciphers a large quantum computer could defeat?

(A) Digital signatures where one most widely used signature algorithm is called ECDSA
(B) Hash functions where the most commonly used hash function is called SHA256

If you think this is a no-brainer and Digital signatures option (A) is the obvious answer, think again. It really depends on when a fault-tolerant quantum computer with enough logical qubits is built, according to Victoria Riess.
