they are currently down to just a month to crack RSA?

> "In 2019, Craig Gidney at Google Quantum AI co-authored a paper that reduced these requirements from 170 million to 20 million quantum bits, or qubits."

> "And in 2025, Gidney devised a way to slash that number to less than a million qubits. Now, Paul Webster at Iceberg Quantum in Australia and his colleagues have managed to decrease the number even further to about 100,000 qubits"

> "Given this connectivity, the team estimated that for 98,000 superconducting qubits, like those currently made by IBM and Google, it would take about a month of computing time to break a common form of RSA encryption"

> "Accomplishing the same in a day would require 471,000 qubits"
