IBM prioritises quality and modular systems with Heron
IBM unveiled its Heron processor and Quantum System Two architecture, emphasising lower error rates and modular expansion.
Connie Zhou for IBM The announcement reflected a shift away from celebrating qubit count alone. Useful circuits require qubits that remain coherent, perform accurate gates and can be connected through a scalable architecture. Company-defined “quantum utility” still did not equal fault-tolerant general advantage.
