PANews reported on October 14 that according to the South China Morning Post, a research team from Shanghai University successfully used a quantum computer produced by Canada's D-Wave Systems to crack a variety of common encryption algorithms for the first time. These algorithms include Present, Gift-64 and Rectangle, which are representative encryption methods of the SPN (Permutation-Substitution Network) structure, and the SPN structure is one of the core components of the current Advanced Encryption Standard (AES). This breakthrough marks the first time that quantum computers have posed a "real and substantial threat" to existing password protection mechanisms, especially encryption technologies widely used in key areas such as banking and the military.
