Google's quantum team found that breaking RSA encryption—used in Bitcoin wallets and banking—may require 20 times fewer qubits than previously thought. Researcher Craig Gidney said a 2048-bit RSA key could now be cracked in under a week using fewer than 1 million noisy qubits, down from the 20 million estimated in 2019. While Bitcoin uses ECC, a similar cryptographic method, this breakthrough suggests its security timeline may also shorten. https://t.co/Re6spNKwuw
