    "body_text": "Researchers at the Flatiron Institute and Boston University used tensor-network methods to compress quantum many-body states that would be impossibly large if represented directly. Their classical calculations covered hundreds of interacting qubits on square, cubic, and diamond lattices; some simulations ran on a laptop and agreed with theory and quantum-computer results. The Science paper challenges a prior claim that this problem class was already beyond classical reach. It does not show that classical machines can efficiently reproduce every quantum computation.",
