IBM has introduced its newest and most powerful quantum processor, called IBM Quantum Nighthawk. The company says Nighthawk is a key step toward showing quantum advantage by 2026 and building fault-tolerant quantum computers by 2029.
Nighthawk will reach IBM users before the end of 2025. The chip holds 120 qubits and uses 218 new tunable couplers set in a square grid. IBM says this layout gives over 20% more links between qubits than its prior Heron chip, which lets users run circuits about 30% more complex while keeping error levels low.
The design can handle workloads of up to 5,000 two-qubit gates today. IBM plans upgrades that should raise that to 7,500 gates in 2026, 10,000 in 2027, and about 15,000 in 2028. By then, the company expects systems could connect 1,000 or more qubits using long-range couplers first tested last year.
“There are many pillars to bringing truly useful quantum computing to the world,” said Jay Gambetta, Director of IBM Research and IBM Fellow. “We believe that IBM is the only company that is positioned to rapidly invent and scale quantum software, hardware, fabrication, and error correction to unlock transformative applications. We are thrilled to announce many of these milestones today.”
IBM expects the research community to confirm the first true cases of quantum advantage by the end of 2026. To support verification, the firm has teamed up with Algorithmiq, the Flatiron Institute, and BlueQubit to start an open, community-led quantum advantage tracker that will track and test claims.
Quantum computing? Just another overhyped tech trend. Stick to traditional methods.
Uh, do we really need quantum tech? Seems like a waste of resources.
Quantum computing is overrated. Stick to traditional tech! #controversialopinions
Quantum computing is overhyped. Stick to classic tech! 🤷♂️
Quantum computing is overrated. Stick to traditional tech for real progress.
