A quantum computer that can chew through more than 100,000 circuits a second is about to land at the foot of the Swiss Alps. IBM and Lockheed Martin announced on September 10 that they are installing a new IBM Quantum System Two at ETH Zurich, and the chip inside it, the IBM Nighthawk r2, is the real story here. It is not just a bigger processor. It is a machine built to hold onto accuracy while running circuits far more complex than anything its predecessors could handle.
What Makes the IBM Nighthawk r2 Different
Numbers alone tell part of the story.
- 120 programmable qubits
- Circuit throughput up to 25 times higher than IBM’s older Heron processors
- Accurate computations on circuits containing 7,500 gates
But raw speed means little if the results are noise. That 7,500-gate benchmark matters because longer, denser circuits are exactly what real chemistry and materials problems demand. Every added gate is another chance for errors to creep in, so holding accuracy at that scale is the harder engineering problem, and it is the one IBM is claiming to have cracked.
Why does gate depth matter so much? Useful quantum algorithms, the kind that model a battery electrolyte or a new catalyst, do not run in a handful of steps. They need thousands of operations chained together without the answer dissolving into noise. A chip that can only stay coherent for short, shallow circuits is a lab curiosity. One that holds up at 7,500 gates starts to look like a tool.
Picture Diego, a 45-year-old supply-chain analyst and father of two who tracks EV battery prices for his job. He has never heard of a qubit, but he cares a lot about whether his family’s next car gets cheaper or more expensive. Materials simulations like the ones this chip is built for are exactly the kind of research that could shorten the years-long path to better, less expensive battery chemistry.
Why ETH Zurich, and Why Now
IBM will install the system at the Swiss National Supercomputing Centre in Lugano and bring it online by the end of 2026, under a three-year agreement running through 2029. ETH Zurich gets Switzerland’s first IBM quantum computer, and researchers there plan to point it at materials science, chemistry simulations, and quantum algorithm development. Lockheed Martin, meanwhile, is funding part of the deployment through an offset arrangement with the Swiss government and plans to use the machine for quantum sensing and additive manufacturing research of its own.
ETH President Joel Mesot called it access to “essential research infrastructure” for training the next generation of quantum scientists. Physics professor Renato Renner pointed to the more practical motivation: classical computers hit a wall simulating quantum mechanical systems, and that is precisely where a machine like this can pick up the slack.
Turning a Faster Chip Into Useful Work
Hardware gains like this only matter if they translate into applications people can actually use, and that is the trend worth watching across the field right now. It echoes what Qedma showed with its quantum chemistry error-mitigation software and the error-correction gains behind Quantinuum’s Helix architecture: the industry is shifting from chasing qubit counts to proving the machines can hold accuracy long enough to be useful. The Nighthawk r2 does not solve quantum error correction on its own, but a 25x throughput jump paired with reliable 7,500-gate circuits gives researchers in Lugano a genuinely bigger sandbox to test ideas in.

Two things worth watching over the next three years: whether ETH Zurich’s researchers publish results that actually use the full 7,500-gate depth, and whether other national labs copy the funding model of pairing a major cloud quantum provider with a supercomputing center and an industry partner footing part of the bill. Either one would be a stronger signal of progress than another qubit-count headline.
