Quantum computers can break all existing encryption algorithms instantly.
- True
- False
Answer: False
Quantum computers threaten asymmetric algorithms like RSA and ECC using Shor's algorithm, but not all encryption. Symmetric algorithms (AES) require larger key sizes for quantum resistance. Post-Quantum Cryptography (PQC) is being standardized by NIST. Practical large-scale quantum computers capable of breaking encryption are still years away.
