They compressed the wave function of hundreds of entangled qubits using tensor networks. ## The Power of Mathematics and Algorithms Researchers pushed the limits of classical computers by compressing complex quantum wave functions using mathematical methods. This approach sparked new debates about the future of quantum computing. ## Tensor Networks: Compressing the Wave Function Led by Joseph Tindall, the team described tensor networks as 'a zip file for the wave function.' This method enabled more efficient modeling of quantum systems. ## The Future of Quantum Simulations The paper published in Science in May 2026 opened new avenues for researching quantum dynamics and materials. The same method can also be applied to optimization problems. ## Boundaries of Classical and Quantum Computing This study showed that classical computers can solve problems thought to require quantum computing. However, it does not diminish the importance of quantum computers but redefines the boundaries. ## A Significant Step for the Future of Technology This discovery reevaluates the relationship between quantum computing and classical computers. The power of mathematics and algorithms continues to be the key to technological advancement. ## Sources covering this story - https://news.bitcoin.com/an-ai-just-solved-a-quantum-problem-on-an-ordinary-laptop-that-was-supposed-to-need-a-quantum-computer-49201/ — --- _Summary written by Brifing from the original reporting.
