A collaborative experiment between researchers at IBM Quantum and UC Berkeley shows quantum computers delivering reliable, accurate results for challenging simulation problems at a scale of 127 qubits. This scale is far beyond exact brute force methods on the most powerful classical computer. The research demonstrates that only two options now exist for solving quantum simulation problems at this scale: (1) classical approximation methods, which are more scalable but less accurate than exact classical methods, and (2) quantum hardware.
