IBM solves the main problem of quantum computing: verification without supercomputers
Quantum computing has long remained a promising but extremely difficult technology to implement. The main stumbling block is the high error rate and the inability to verify the results of quantum processors using classical methods. IBM, together with partners Qedma and Algorithmiq, has presented two studies that radically change the situation, offering not only the execution of tasks beyond the reach of classical supercomputers but also reliable verification of the obtained data.
Overcoming the Classical Limit
In the first study, IBM and Qedma demonstrated error suppression technology on the IBM Quantum Heron processor. The system solved a quantum material modeling problem that could no longer be reproduced with sufficient accuracy on classical supercomputers, including Japan's Fugaku. The key result is not just a demonstration of computational power, but the generation of a trusted result despite inevitable hardware noise.
A New Verification Paradigm
The second study, conducted jointly with Algorithmiq, represents a breakthrough in the field of quantum computing verification. When a classical computer can no longer independently recalculate the answer, traditional verification becomes impossible. IBM proposed a methodology based on statistical tests and independent control mechanisms, allowing the reliability of the result to be assessed without full classical recalculation. This opens the path to the practical use of quantum systems in materials science, chemistry, and pharmaceuticals.
The Era of "Trusted Computing"
IBM defines these achievements as a transition to the concept of Trusted Quantum Computation. If previously the industry was chasing "quantum supremacy," the focus is now shifting to provable correctness of computations. Experts rightly note that solving the trust problem could become a milestone no less important than supremacy over classical computers. It was precisely the lack of guarantees regarding the correctness of results that long hindered the commercialization of the technology.
My assessment: The solutions presented by IBM are not just a step forward, but a paradigm shift. If the verification methodology without a classical computer is successfully scaled, we will witness the beginning of a true practical era of quantum computing. In the next two to three years, it will be these algorithms, not raw power, that will become the main driver for the adoption of quantum processors in industry.
