CRQC (Cryptographically Relevant Quantum Computer)
A cryptographically relevant quantum computer is a quantum computer powerful enough to break real-world cryptographic systems, specifically one that can run Shor's algorithm at scale to derive private keys from public keys.
No CRQC exists today. Current estimates suggest one would require approximately 6,000 logical qubits and over 100 million fault-tolerant operations, translating to roughly 9.4 million physical qubits. As of early 2026, public demonstrations have achieved roughly 24 to 28 logical qubits. Most researchers estimate CRQCs are 10 to 30 years away.
