Quantum Beats Supercomputers: The Future of IT Infrastructure

A D-Wave quantum annealer is reportedly able to perform a simulation in a matter of minutes that would take a supercomputer a million years to complete. However, doubts have been raised about this claim.

The Essentials

• D-Wave claims quantum supremacy with a simulation of spin glasses that would take supercomputers millions of years.
• Quantum annealers utilize quantum tunneling effects for faster solutions to optimization problems.
• This experiment has practical utility, unlike previous academic quantum experiments.
• D-Wave already deploys commercial quantum annealers, while other manufacturers have only prototypes.
• The Jülich research center has been using a D-Wave machine for research purposes since 2022.

Quantum computers are still in the early stages of development. Many breakthroughs, if they occur, are purely hypothetical. This could change with a quantum annealer from D-Wave Quantum Inc.

Annealing, in metal or glass processing, means heating to a specific temperature to prevent brittleness or cracking. Quantum annealing is based on a similar principle. “In a quantum annealer, qubits work that cannot be universally connected using gates, but are able to find global minima for optimization problems faster and better than conventional computers through real quantum tunneling effects,” explains the German Quantum Alliance.

The Canadian company D-Wave, with its US headquarters in Palo Alto, California, announced a breakthrough in the Science magazine on March 13, 2025, which, according to the Heise magazine c’t, had its preliminary work dating back to 2023.

Alleged First True Supremacy

According to this, the company claims to have succeeded with a quantum annealer in executing a simulation that would require a supercomputer to use a million years and more energy than the entire world population consumes in a year. And this is said to prove quantum supremacy. This refers to the superiority or “quantum advantage” over classical supercomputers, meaning the ability to solve a specific problem within a realistic time frame.

There have been several such alleged breakthroughs before. For example, Google claimed to have provided evidence of quantum supremacy in December 2024 with its new quantum chip “Willow”. The core problem with such experiments has always been that the problems solved were primarily academic and had no practical use.

In this case, it’s different. “Our demonstration of the superiority of quantum computers on a useful problem is an industry first,” says D-Wave CEO Alan Baratz, and continues: “All other claims that quantum systems outperform classical computers have been disputed and concerned the generation of random numbers without practical value.”

Jens Eisert, quantum researcher at the Free University of Berlin, praises the work, calling it “a highly exciting piece of research that looks for quantum advantages in the right place.”

The Advantage Lies in Quantum Technology

The researchers from D-Wave simulated the behavior of highly complex magnetic materials known as “spin glasses” in their experiment, which are relevant for research and for solving optimization problems.

Typically, such optimization problems are simulated by supercomputers. However, the qubits (quantum bits) of quantum annealers already possess quantum mechanical properties that a classical (super)computer must simulate first.

According to Eisert, the D-Wave machine is not yet a full-fledged quantum computer, but a “quantum annealer that can accurately replicate model systems from solid-state physics”. Such an annealer is specifically designed to solve optimization problems, for example in materials research, on the financial market, and for machine learning.

As heise and c’t further report, D-Wave is already commercially selling such quantum annealers, while other manufacturers have only presented prototypes of quantum chips so far. For example, such a machine from D-Wave has been installed at the Jülich research center since 2022.

In this case, the researchers entrusted both the D-Wave machines Advantage 1 and 2, as well as the Frontier supercomputer at the Oak Ridge National Laboratory of the US Department of Energy, with the problem. The Frontier, also known as OLCF-5, has been the world’s fastest supercomputer since its commissioning in 2022, with 1.1 exaFLOPS (floating-point operations per second).
