ARMONK, NY, 14 June 2023 /PRNewswire/ — IBM (NYSE: IBM) today announced a new breakthrough, published on the cover of the scientific journal Natureand demonstrates for the first time that quantum computers can produce accurate results at the scale of 100+ qubits, exceeding leading classical approaches.

One of the ultimate goals of quantum computing is to simulate components of materials that classical computers have never effectively simulated. Being able to model these is a crucial step towards the ability to tackle challenges such as designing more effective fertilizers, building better batteries and creating new medicines. However, today’s quantum systems are inherently noisy and produce a significant number of errors that hamper performance. This is due to the fragile nature of quantum bits or qubits and perturbations from their environment.

In their experiment, the IBM team demonstrates that it is possible for a quantum computer to outperform leading classical simulations by learning and mitigating errors in the system. The team used the IBM Quantum ‘Eagle’ quantum processor composed of 127 superconducting qubits on a chip to generate large, entangled states that simulate the dynamics of spins in a material model and accurately predict properties such as its magnetization.

To verify the accuracy of this modeling, a team of researchers at UC Berkeley simultaneously performed these simulations on advanced classical computers located at Lawrence Berkeley National Lab’s National Energy Research Scientific Computing Center (NERSC) and Purdue University. As the scale of the model increased, the quantum computer continued to provide accurate results using advanced error-limiting techniques, even as classical computing methods eventually faltered and were no match for the IBM Quantum system.

“This is the first time we have seen quantum computers accurately model a physical system in nature beyond leading classical approaches,” said Darío Gil, Senior Vice President and Director of IBM Research. “For us, this milestone is an important step in proving that today’s quantum computers are capable, scientific tools that can be used to model problems that are extremely difficult – and perhaps impossible – for classical systems, signaling that we are now going into a new era. of utility for quantum computing.”

IBM commits to Utility-Scale Processors across IBM Quantum Systems

Following this groundbreaking work, IBM is also announcing that its IBM Quantum systems, running both in the cloud and on-site at partner locations, will be powered by a minimum of 127 qubits to be completed over the next year.

These processors provide access to computational power large enough to outperform classical methods for certain applications and will offer improved coherence times as well as lower error rates compared to previous IBM quantum systems. Such properties can be combined with constantly advancing error-control techniques to enable IBM Quantum systems to meet a new threshold for industry that IBM has called ‘utility-scale’, a point where quantum computers can serve as scientific tools for exploring a new scope of problems that classical systems may never be able to solve.

“As we move forward in our mission to bring useful quantum computing to the world, we have solid evidence of the cornerstones needed to explore a whole new class of computational problems,” said Jay Gambetta, IBM Fellow and Vice President, IBM Quantum. “By equipping our IBM Quantum systems with processors capable of scale, we invite our customers, partners and collaborators to bring their toughest problems to explore the limits of today’s quantum systems and start extracting real value.”

All IBM Quantum users will be able to run problems on utility-scale processors larger than 100 qubits. The more than 2,000 participants in the IBM Quantum Spring Challenge had access to these utility-scale processors as they explored dynamic circuits, a technology that makes it easier to run more advanced quantum algorithms.

Global researchers and industry leaders pursue value with IBM Quantum
