Apple already includes end-to-end encryption in its secure iMessage platform. But while elements such as Contact Key Verification can help keep users secure from current-generation computing threats, it could have a hard time taking on quantum computing.
To thwart quantum computers when they eventually become more commonly used, Apple is not waiting until they arrive to bolster its security.
