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.

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon called the Talbot effect,

Google researchers found certain quantum computers could break the encryption protecting the world’s largest cryptocurrency.

Network encryption was designed for a world in which adversaries needed to break cryptography in real time to extract value. That world is shifting.

Instagram will stop supporting end-to-end encryption in May, and affected messages may need to be downloaded beforehand.

Apple tested end-to-end encryption (E2EE) for RCS messages exchanged between iPhone and Android users in the iOS 26.4 beta, but Apple made it clear the functionality was not going to launch in the iOS 26.

OS 26.5 beta 1 gives the Messages app support for end-to-end encrypted RCS messaging, after previously being available in the iOS 26.4 beta.
