IBM Delivers New Quantum Processors, Software, and Algorithm Breakthroughs on Path to Advantage and Fault Tolerance

With quantum advantage expected by 2026, real breakthroughs are coming fast and the countdown for non–quantum-resistant blockchains is ongoing.

The new Nighthawk processor delivers 120 qubits, 30% greater circuit complexity, and a 10x improvement in error-correction decoding speed. IBM is targeting fault-tolerant quantum computing by 2029. This marks a major step toward practical quantum systems and a reminder that current cryptography and blockchain security will eventually face real quantum threats.
