Google has presented a study stating that its team working on quantum computing has discovered that cracking RSA encryption, used to protect data such as bank accounts and bitcoin wallets, will require significantly fewer quantum resources than previously thought – about 20 times. In 2019, Google's Craig Gidney and his colleagues demonstrated that Shor's algorithm can handle the destruction of standard-length RSA keys (2048 bits) in 8 hours using a quantum computer with a capacity of 20 mil... 阅读更多
