Google has announced a breakthrough in quantum computing, with an algorithm that performed a task beyond the capability of classical supercomputers. The algorithm successfully computed the structure of a molecule, a feat that could pave the way for advances in medicine and materials science.
In a blog post, Google stated: “This is the first time in history that any quantum computer has successfully run a verifiable algorithm that surpasses the ability of supercomputers.” The results were published in a peer-reviewed paper in Nature on Wednesday.
Michel Devoret, chief scientist at Google’s quantum AI unit and recent Nobel laureate, called the announcement a milestone. The algorithm enabled the quantum computer to operate 13,000 times faster than a classical computer.
However, experts caution that practical applications remain distant. Winfried Hensinger, professor of quantum technologies at the University of Sussex, noted that the task was narrow and not yet revolutionary. Fully fault-tolerant quantum computers would require millions of qubits, far beyond current hardware capabilities.
Google’s vice-president of engineering, Hartmut Neven, expressed optimism that real-world uses could emerge within five years. The company also believes quantum computers could generate unique data to enhance AI models.
