IBM has unveiled findings from two collaborative research projects with Qedma and Algorithmiq, paving the way for practical applications of quantum computers.

The partners showcased methods that not only perform calculations beyond the reach of classical supercomputers but also verify the accuracy of the results. According to IBM, this addresses one of the major challenges currently facing the quantum computing industry.

Quantum Computing Surpasses Classical Models

In the first study, IBM and Qedma employed error suppression technology to model the behavior of quantum materials using the IBM Quantum Heron processor.

The company reported that the system successfully tackled a problem whose results could no longer be reliably reproduced using the best classical methods, including computations on Japan's Fugaku supercomputer.

Researchers emphasized that the key achievement lies not just in the computation itself, but in the ability to obtain results that can be trusted despite the inevitable errors inherent in quantum hardware.

Verification Without a Classical Computer

In the second study, IBM and Algorithmiq introduced a verification methodology for quantum computations in scenarios where classical computers can no longer independently validate the answers. This new approach relies on statistical tests and independent control mechanisms that allow for assessing the validity of results without complete classical recalculation.

IBM believes that such methods will be essential for utilizing quantum computers in fields like materials science, chemistry, and pharmaceuticals.

A New Phase in Industry Development

The findings from IBM are viewed as a shift towards the concept of Trusted Quantum Computation.

While the industry previously focused on demonstrating so-called quantum supremacy, the emphasis is now shifting towards proving that computations are indeed correct, experts noted in comments to Barron’s. They argue that this could represent a milestone as significant as achieving an advantage over classical computers, given that trust has long been a major barrier to the commercial adoption of quantum technologies.

It is worth noting that in May, Petra Florizun, the global sales director for IBM Quantum, announced the onset of a practical era for quantum computing.
