IBM launched its latest quantum processor, Quantum Nighthawk, designed to deliver circuits with 30% more complexity than previous versions. The processor, which features 120 qubits and 218 tunable couplers, is expected to be delivered to users by the end of 2025.
“There are many pillars to bringing truly useful quantum computing to the world,” said Jay Gambetta, director of IBM Research. “We believe that IBM is the only company positioned to rapidly invent and scale quantum software, hardware, fabrication and error correction.”
IBM also introduced Quantum Loon, an experimental processor that demonstrates all the hardware components required for fault-tolerant quantum computing. The company has achieved a tenfold speed-up in quantum error correction decoding using classical computing hardware, completing the milestone a year ahead of schedule.
The company announced these advancements in its quantum computing roadmap at the annual Quantum Developer Conference, introducing new processors, software updates and algorithmic breakthroughs.
The developments are aimed at achieving quantum advantage by 2026 and fault-tolerant quantum computing by 2029.
IBM stated that future versions of the Nighthawk processor will achieve up to 15,000 two-qubit gates by 2028, with verified demonstrations of quantum advantage anticipated by 2026.
In collaboration with Algorithmiq, the Flatiron Institute and BlueQubit, IBM has contributed three experiments to an open community quantum advantage tracker to verify emerging results.
Sabrina Maniscalco, CEO of Algorithmiq, said, “We are seeing promising experimental results, and independent simulations validate its classical hardness.” BlueQubit’s CTO, Hayk Tepanyan, added that their work supports “instances where quantum computers are starting to outperform classical computers by orders of magnitude.”
To support these advancements, IBM has enhanced its open-source quantum software, Qiskit. The company reported a 24% increase in accuracy using dynamic circuits and a 100-fold reduction in result extraction costs through HPC-powered error mitigation.
To accelerate quantum chip production, IBM has transitioned fabrication to a 300mm wafer facility at the Albany NanoTech Complex. The move has doubled development speed and increased chip complexity tenfold, according to IBM.
The company stated that these milestones collectively demonstrate progress toward scalable, high-fidelity quantum systems capable of addressing scientific and industrial challenges.
