Imagine a master key capable of unlocking every vault in Tokyo\u2019s financial district overnight, not through physical force, but mathematical supremacy. This isn\u2019t speculative fiction; it\u2019s the imminent reality of quantum computing. Current encryption standards like RSA and ECC, which safeguard everything from bank transfers to national security communications, could disintegrate under quantum processing power. For Japan\u2019s business leaders, this represents more than a technical curiosity. It\u2019s an existential threat to economic stability and corporate sovereignty. The vulnerability lies in Shor\u2019s algorithm, a quantum approach that factors large numbers exponentially faster than classical computers. Once practical quantum machines arrive, experts suggest a decade or sooner, data encrypted today could be
