With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100,000 qubits and 10 days to break, according to the researchers, from Caltech and quantum computing company Oratomic in Pasadena, Calif.

Google's new whitepaper says it could take only minutes for a quantum system to crack Bitcoin.

Quantum-safe drones use advanced encryption to secure UAV communications against evolving cyber threats and quantum attacks

A team of Google researchers just set a new date for post-quantum cryptography migration: 2029. Among other things, this means that Bitcoin, as well as many other cryptocurrencies, needs to adopt new cryptographic techniques that are resilient to quantum attacks within three years.
