2025 marks a turning point in the quantum race. Japan has unveiled a superconducting computer with 256 qubits, the most powerful ever designed in this format. A few days later, China struck hard by activating a system exceeding 1,000 qubits. Even better, Beijing announces concrete industrial goals in the next 18 months. But one event shakes global cybersecurity: a Chinese team has reportedly managed to break RSA encryption using a quantum machine. These advancements render classical cryptographic systems obsolete, including those currently used by blockchains.
