International Business Machines Corp. (NYSE:IBM) announced a series of quantum computing milestones at its annual Quantum Developer Conference, underscoring progress toward achieving quantum advantage by 2026 and fault-tolerant quantum computing by 2029.
IBM Quantum Nighthawk Targets Next-Level Complexity
At the center of IBM’s announcement is the IBM Quantum Nighthawk, a next-generation 120-qubit processor featuring 218 tunable couplers—20% more than its predecessor, the IBM Quantum Heron. The enhanced connectivity allows users to execute circuits with 30% greater complexity while maintaining low error rates.
The first Nighthawk units are expected to reach users by late 2025, capable of handling circuits with up to 5,000 two-qubit gates. IBM projects that capacity will rise to 7,500 gates by 2026, 10,000 by 2027, and 15,000 by 2028 through long-range coupler integration.
