Explore the current state of quantum computing's threat to AES encryption through a comprehensive evaluation of leading quantum processors from IBM, Google, Zuchongzhi 2, Microsoft, Rigetti, IonQ, and Honeywell. Analyze quantum gate complexity, qubit coherence time, and scalability trade-offs to understand how these systems could potentially compromise AES security when scaled to thousands of qubits with error correction capabilities. Examine the timeline for quantum threats to cryptographic systems and discover strategic approaches for mitigation and post-quantum cryptography (PQC) migration planning. Learn about methods to enhance AES robustness through longer key sizes and hybrid cryptographic models to strengthen overall cryptographic readiness against emerging quantum computing capabilities.
